NSIS Error - can't uninstall 7.1.6 Guest Additions from windows 10

[vbox_user33]

When attempting to uninstall Guest Additions from multiple Win10 (22H2) guest, fails with an NSIS Error: Installer integrity check has failed... Contact the installer's author to obtain a new copy. ​​http://nsis.sf.net/NSIS_ERROR I have tried this on several different VMs running the same version of Win10 and always get the error making clean uninstall impossible - when trying to install previous version over the top, and uninstall it almost works, but will hang up shutdowns causing forced poweroff/file corruption. Please fix this.

Reroduced with the 7.1.6 Guest Additions ISO.

A work around to uninstall those will be to start the uninstallation via

uninst.exe /NCRC

This will skip the integrity checks.

Investigating.

Please have a try with the latest 7.1 Guest Additions test build -- there the issue should be fixed already.
