During some deployment, the installation cannot update or uninstall previous versions. So here’s a autoit script I created to allows to scan the registry to detect and uninstall previous versions. So, to be successfull you must modify the values of
$Software = “Adobe reader”
$apps1 = “C:\Adobe\fr\AcroRead.msi”
$Mst = “C:\Adobe\fr\AcroRead.mst”
If $DisplayVersion > “10.1.3”
in the autoit script. Finally, the application must support this uninstall method.
