问题
In my inno setup RUN selection I force silent install of MSVCRT. I wonder how to make it install itself only if not yet installed?
This is what I call now:
Filename: {tmp}\\vcredist_x86.exe; Parameters: \"/passive /Q:a /c:\"\"msiexec /qb /i vcredist.msi\"\" \"; StatusMsg: Installing 2010 RunTime...

Since you don't want to tell what minimal version of Visual C++ redistributable package you require, here you have the code sample from which you can build this by your own. Please notice that I have no clue, what versions are compatible with what and what lower versions must be installed, I'll keep this upon you.
The only thing I can tell you is that you should definitely use Check conditional parameter, the solutions attempting to install the framework or runtime libraries when the wizard is being opened are wrong. This conditional parameter works as when you return True to it, the file is being installed, if False it is skipped. So you need to return True to VCRedistNeedsInstall function when you want to install your runtime libraries, False if not. The helper function VCVersionInstalled which uses constants beginning with the VC_ here returns True when the package is installed, False otherwise.
As the source of this I've used the following sources:
- How to detect the presence of the VC 8.0 runtime redistributable package
- How to detect the presence of the VC 9.0 runtime redistributable package
- How to detect the presence of the VC 2010 runtime redistributable package
The following code should be compatible with Unicode and ANSI versions of Inno Setup thanks to kobik's idea to use the conditional define.
Here is the code:

Source: "vcredist_x86.exe"; DestDir: {tmp}; Flags: deleteafterinstall
[Run]
; add the Parameters, WorkingDir and StatusMsg as you wish, just keep here
; the conditional installation Check

Update by chuckleplant:
Added VC++ 2012 product codes. Notice that the redistributable package installs two things, the minimum runtime and the additional runtime. It should be enough for you to look for the minimum runtime. Testing against the Microsoft Visual C++ 2012 Redistributable product code will give INSTALLSTATE_UNKNOWN, use the Minimum Runtime codes instead. It's the same situation for VC++ 2013 and 2015.
You can find product codes for other Visual Studio versions in HKEY_CLASSES_ROOT\Installer\Dependencies\, for example HKEY_CLASSES_ROOT\Installer\Dependencies\Microsoft.VS.VC_RuntimeAdditionalVSU_amd64,v14

Here's a version that uses the Microsoft recommended way of determining whether the VC Redistributable is installed. I only needed VC 2015 so you will need to adapt values and parameters for other versions:
[Files]
Source: ".\vc-redist\vc-redist\win64\bin\vc_redist.x64.exe"; DestDir: "{tmp}"; Flags: deleteafterinstall; Check: Is64BitInstallMode
; FlexLM requires the VC 2015 redistributables so run the installer if this
; or a later 2015 version is not already present
[Run]
Filename: "{tmp}\vc_redist.x64.exe"; Parameters: "/install /passive"; StatusMsg: "{#VCmsg}"; Check: IsWin64 and not VCinstalled
[Code]
function VCinstalled: Boolean;
// Function for Inno Setup Compiler
// Returns True if same or later Microsoft Visual C++ 2015 Redistributable is installed, otherwise False.
var
major: Cardinal;
minor: Cardinal;
bld: Cardinal;
rbld: Cardinal;
key: String;
begin
Result := False;
key := 'SOFTWARE\Microsoft\VisualStudio\14.0\VC\Runtimes\x64';
if RegQueryDWordValue(HKEY_LOCAL_MACHINE, key, 'Major', major) then begin
if RegQueryDWordValue(HKEY_LOCAL_MACHINE, key, 'Minor', minor) then begin
if RegQueryDWordValue(HKEY_LOCAL_MACHINE, key, 'Bld', bld) then begin
if RegQueryDWordValue(HKEY_LOCAL_MACHINE, key, 'RBld', rbld) then begin
Log('VC 2015 Redist Major is: ' + IntToStr(major) + ' Minor is: ' + IntToStr(minor) + ' Bld is: ' + IntToStr(bld) + ' Rbld is: ' + IntToStr(rbld));
// Version info was found. Return true if later or equal to our 14.0.24212.00 redistributable
// Note brackets required because of weird operator precendence
Result := (major >= 14) and (minor >= 0) and (bld >= 24212) and (rbld >= 0)
end;
end;
end;
end;
end;

I know is very old question but i encounter this situation and since i couldn't do winregistry checking i did this approach,
based on this list of files : https://matthew-brett.github.io/pydagogue/_sources/python_msvc.rst.txt
i was able to just check if the file exist , for example VCRedist 2015/2013 x86/x64:
2015
C:/Windows/SysWOW64/msvcp140.dll - x64
C:/Windows/System32/msvcp140.dll" - x86
2013
C:/Windows/SysWOW64/msvcp120.dll - x64
C:/Windows/System32/msvcp120.dll" - x86
