Error 1720 During Installation

Last updated: Monday, March 29, 2021

Applies to: ProVal and ProAdmin


When installing ProVal you get a 1720 error and the install fails.


Delete the following folder and try the install again C:\Users\%username%\AppData\Local\VirtualStore\Program Files (x86)\WinTech


A virtual copy of the previous ProVal installation was created by windows and needs to be deleted before installing a new version of ProVal.
