JSI Tip 8700. How can I determine if an application is installed on a remote computer?

I have scripted Installed.bat to determine if an application is installed on a remote computer.

The syntax for using Installed.bat is:

Installed ComputerName DisplayName_Or_SubKey Answer

Where:

ComputerName          is the NetBIOS name of the remote computer.DisplayName_Or_SubKey is either the sub-key of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall or the contents of the DisplayName Value Name.Answer                is a <a href="https://www.itprotoday.com/article/jsifaq/jsi-tip-5535-how-can-i-cause-a-called-batch-file-to-return-a-call-directed-environment-variable-.aspx">call directed environment variable</a> that will contain a Y or an N.

NOTE: Installed.bat uses REG.EXE, built into Windows XP and latter, or installed from the Support Tools on the Windows 2000 CD-ROM.

Installed.bat contains:

@echo offIf {%3}

NOTE: To uninstall the program remotely, use PsExec.exe to run the string in the UninstallString Value Name. To locate the UninstallString, run UninstallString ComputerName, where UninstallString.bat contains:

@echo offIf {%1}{} @echo Syntax: UninstallString ComputerName&goto :EOFsetlocalset key=\%1HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall /sfor /f "Tokens=*" %%a in ('reg query %key%^|FINDSTR /I /L "HKEY_LOCAL_MACHINE DisplayName UninstallString"') do ( @echo %%a)endlocal
