Scenario: using SQL Server 2008 R2 Express under Windows 7 without problems.
Then I upgraded to Windows 10 without problems.
Then I downgraded back to Windows 7 (due to problems with other applications). SQL Server is gone.
When I run
x64_ENU + SQLEXPR_x64_ENU to reinstall I get the following error message during "Setup Support Files" (with
ExecuteStandardTimingsWorkflow apparently the current task) and cannot go further:
Microsoft SQL Server 2008 R2 Setup The following error has occurred: An error occurred during the installation of assembly 'policy.8.0.Microsoft.VC80.CRT,version="8.0.50727.42",type="win32-policy", processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b"'.
SFC /SCANNOW did not reveal any problems.
Program_Install_And_Uninstall also did not. Microsoft Visual C++ 2005 Redistributable Package (x64) was not installed, so I installed it.
Now SQL Server 2008 R2 Setup ran a lot further, but then generated a similar (but not identical) error at
The following components were installed:
- SQL Server 2008 R2 Native Client
- SQL Server 2008 R2 Policies
- SQL Server 2008 R2 setup (English)
- SQL Server Compact 3.5 SP2 ENU
- SQL Server Compact 3.5 SP2 Query Tools ENU
Deleting all these, and also all components of Visual Studio, and trying again did not change this.
