To rename numbered folders
Open Windows Explorer and go to: <drive>:\program files\common files\Installshield\drivers
In the right pane, right-click a numbered folder and click rename. Change the name to Xold.
Where Xold is the number of the folder like 1 and you add the text old. The result is 1old.
Rename all numbered folders.
Run the installation. Installshield files should now update.
