Error 1718. *.msp Did Not Pass The Digital Signature Check

Visual Studio 2005 Service Pack 1 Install Problem: “Error 1718. *.msp did not pass the digital signature check “

I was trying to install the Visual Studio 2005 Service Pack 1 on Visual Studio 2005 Standared Edition on Windows Server 2003 but after around 10 minutes the installation stops throwing the following error:

“Error 1718. File 5fc5ca.msp did not pass the digital signature check”

(The file name might be different for your installation.)

I have searhed Google for the same and found the following workaround.

  1. Click Start, click Run, type control admintools, and then click OK.

  2. Double-click Domain Security Policy (Local Security Policy).

  3. Click Software Restriction Policies. If no software restrictions are listed, right-click Software Restriction Policies, and then click Add New Policy.

  4. Under Object Type, double-click Enforcement.

  5. Click All users except local administrators, and then click OK.

  6. Restart the computer.

  7. Install the Service Pack.
