Microsoft Visual Studio 2015 Free Download Offline Installer

Posted : admin On 1/26/2022
  1. I have a Resharper 9x license and it is only compatible up to MS VS Community 2015 edition. I tried to download the 2015 version from Microsoft but their website stubbornly wants me to have 2017, only. Can someone please provide me a url to the 2015 edition? Or, explain how to navigate Microsoft's site to obtain the 2015 edition? Update on solution.
  2. However, using their instructions it installs Visual Studio 2017, then installs the SSDT onto this version, when it's on the setup screen it only gives the option to install onto Visual Studio 2017.

Visual Studio is primarily designed to be installed on an internet-connected machine, since many components are updated regularly. However, with some extra steps, it's possible to deploy Visual Studio in an environment where a working internet connection is unavailable.

The Visual Studio setup engine installs only content that is trusted. It does this by checking Authenticode signatures of the content being downloaded and verifying that all content is trusted before installing it. This keeps your environment safe from attacks where the download location is compromised. Visual Studio setup therefore requires that several standard Microsoft root and intermediate certificates are installed and up-to- date on a user's machine. If the machine has been kept up to date with Windows Update, signing certificates usually are up to date. If the machine is connected to the internet, during installation Visual Studio may refresh certificates as necessary to verify file signatures. If the machine is offline, the certificates must be refreshed another way.

How to refresh certificates when offline

There are three options for installing or updating certificates in an offline environment.

Option 1 - Manually install certificates from a layout folder

When you create a network layout, the necessary certificates are downloaded to the Certificates folder. You can then manually install the certificates by double-clicking each of the certificate files, and then clicking through the Certificate Manager wizard. If asked for a password, leave it blank.

Update: For Visual Studio 2017 version 15.8 Preview 2 or later, you can manually install the certificates by right-clicking each of the certificate files, selecting Install Certificate, and then clicking through the Certificate Manager wizard.

Option 2 - Distribute trusted root certificates in an enterprise environment

For enterprises with offline machines that do not have the latest root certificates, an administrator can use the instructions on the Configure Trusted Roots and Disallowed Certificates page to update them.

Option 3 - Install certificates as part of a scripted deployment of Visual Studio

If you are scripting the deployment of Visual Studio in an offline environment to client workstations, you should follow these steps:

  1. Copy the Certificate Manager Tool (certmgr.exe) to the installation share (for example, serversharevs2017). Certmgr.exe is not included as part of Windows itself, but is available as part of the Windows SDK.

  2. Create a batch file with the following commands:

    Update: For Visual Studio 2017 version 15.8 Preview 2 or later, create the batch file with the following commands:

    Alternatively, create a batch file that uses certutil.exe, which ships with Windows, with the following commands:

  3. Deploy the batch file to the client. This command should be run from an elevated process.

What are the certificates files in the Certificates folder?

The three .P12 files in this folder each contain an intermediate certificate and a root certificate. Most systems that are current with Windows Update have these certificates already installed.

  • ManifestSignCertificates.p12 contains:
    • Intermediate certificate: Microsoft Code Signing PCA 2011
      • Not required. Improves performance in some scenarios if present.
    • Root certificate: Microsoft Root Certificate Authority 2011
      • Required on Windows 7 Service Pack 1 systems that do not have the latest Windows Updates installed.
  • ManifestCounterSignCertificates.p12 contains:
    • Intermediate certificate: Microsoft Time-Stamp PCA 2010
      • Not required. Improves performance in some scenarios if present.
    • Root certificate: Microsoft Root Certificate Authority 2010
      • Required for Windows 7 Service Pack 1 systems that do not have the latest Windows Updates installed.
  • Vs_installer_opc.SignCertificates.p12 contains:
    • Intermediate certificate: Microsoft Code Signing PCA
      • Required for all systems. Note that systems with all updates applied from Windows Update might not have this certificate.
    • Root certificate: Microsoft Root Certificate Authority
      • Required. This certificate ships with systems running Windows 7 or later.

Update: For Visual Studio 2017 version 15.8 Preview 2 or later, the Visual Studio Installer requires only the root certificates to be installed on the system. These certificates are stored in .cer files instead of .p12.

  • ManifestSignCertificates.cer contains:
    • Root certificate: Microsoft Root Certificate Authority 2011
      • Required on Windows 7 Service Pack 1 systems that do not have the latest Windows Updates installed.
  • ManifestCounterSignCertificates.cer contains:
    • Root certificate: Microsoft Root Certificate Authority 2010
      • Required for Windows 7 Service Pack 1 systems that do not have the latest Windows Updates installed.
  • Vs_installer_opc.SignCertificates.cer contains:
    • Root certificate: Microsoft Root Certificate Authority
      • Required. This certificate ships with systems running Windows 7 or later.

The Visual Studio Installer requires only the root certificates to be installed on the system.

Offline

Why are the certificates from the Certificates folder not installed automatically?

When a signature is verified in an online environment, Windows APIs are used to download and add the certificates to the system. Verification that the certificate is trusted and allowed via administrative settings occurs during this process. This verification process cannot occur in most offline environments. Installing the certificates manually allows enterprise administrators to ensure the certificates are trusted and meet the security policy of their organization.

Checking if certificates are already installed

One way to check on the installing system is to follow these steps:

  1. Run mmc.exe.
    a. Click File, and then select Add/Remove Snap-in.
    b. Double-click Certificates, select Computer account, and then click Next.
    c. Select Local computer, click Finish, and then click OK.
    d. Expand Certificates (Local Computer).
    e. Expand Trusted Root Certification Authorities, and then select Certificates.

    • Check this list for the necessary root certificates.

    f. Expand Intermediate Certification Authorities, and then select Certificates.

    • Check this list for the required intermediate certificates.
  2. Click File, and then select Add/Remove Snap-in.
    a. Double-click Certificates, select My user account, click Finish, and then click OK.
    b. Expand Certificates – Current User.
    c. Expand Intermediate Certification Authorities, and then select Certificates.

    • Check this list for the required intermediate certificates.

If the certificates names were not in the Issued To columns, they must be installed. If an intermediate certificate was only in the Current User Intermediate Certificate store, then it is available only to the user that is logged in. You might need to install it for other users.

Install Visual Studio

After you install the certificates, deployment of Visual Studio can proceed by using the instructions from the Deploying from a network installation section of the 'Create a network installation of Visual Studio' page.
