How to detect chrome version information in NSIS script ?

Answer 1

You should look into the current user settings instead of the local machine (or in addition to the local machine if the resulting string is empty):

ReadRegStr $R0 HKCU "${CHROME}" "UninstallString"

Also you should not have a backslash at the beginning of the key path. Did you noticed a warning during the script compilation?

ReadRegStr: registry path name begins with '\', may cause problems
