Detect a software existence in the registry in a Windows batch script

Hello,

I need to write a script to detect a particular software guid exists in the registry on computers and run particular msiexec command line to uninstall it.

For example, if 7B4192A1-84C4-4E90-A31B-B4847CA8E23C exists in HKLM, run msiexec /x {7B4192A1-84C4-4E90-A31B-B4847CA8E23C} /qn

I need to do that in a bat script. Please advise how to do it.

Many thanks.

Where in HKLM specifically will that exist?

You can use REG QUERY in a BAT script to check for it's existence, but you need to know the full path to it.

Thank you. I did a search in the registry and the location to detect the guid looks promising - please see below.

Do you think the below will work?

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{7B4192A1-84C4-4E90-A31B-B4847CA8E23C" >NUL 2>&1 && (msiexec /x {7B4192A1-84C4-4E90-A31B-B4847CA8E23C} /qn

Bill Prew

Yes, but a couple of characters seem to be missing, I think it should be:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{7B4192A1-84C4-4E90-A31B-B4847CA8E23C}" >NUL 2>&1 && (msiexec /x {7B4192A1-84C4-4E90-A31B-B4847CA8E23C} /qn)

HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall and HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall are the keys to query
