Cannot remove a LANSA package installation

Post by Joerg Hamacher » Fri Aug 11, 2017 1:55 am


we installed LANSA via deployment package on a WIndows10 PC.
Now we have to remove the installation again.

When trying to deinstal the package in Windows De-Installation Window the following message appears:
"This install requires elevation. Please execute it from a command prompt which has been Run as Administrator"

What are the correct commands to type in when running the CMD as administrator?

SImpy installing a complete new version of our programs doesn't work either because the LANSA installation says:
"Another version of this product is already installed. Installed version has to be removed"...

Many thanks in advance,

Hi Joerg

See if this helps: ... iexec.html

The /x flag is used to uninstall. You can use the GUID or MSI name to uninstall.

Regards, Hamad
