Question

I'm reading a Registry Key in my NSIS Script to detect wether Microsoft Visual 2010 Redistributable is installed or not.

... ReadRegStr $R0 HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall{DA5E371C-6333-3D8A-93A4-6FD5B20BCC6E}" "DisplayName" ${If} $R0 != "" Messagebox MB_OK "C++ 2010 Redistributable detected" goto yesCpp2010 ${Else} MessageBox MB_OK "C++ 2010 not found" goto noCpp2010 ${EndIf} ...

I tried it on Windows 7 and it works. But it won't work on other Windows Versions if the Programms have other Keys. Do they have the same Keys? If the Keys are different, is there a way to get them?

Was it helpful?

Solution

The GUID can probably change with Service Pack's and security updates but this blog claims you can just check the Installed DWORD under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\x64.

For previous MSVC versions I would also suggest querying SxS but I don't think 2010 uses that technology...

OTHER TIPS

I think you forget "\" character after Uninstall.

ReadRegStr $R0 HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall{DA5E371C-6333-3D8A-93A4-6FD5B20BCC6E}" "DisplayName"
