chromodo_restart_helper.exe does not start the update of chromodobrowser

Trying once again please
Updating Chromodo (previous to v.45.9.12.392, and since many versions during a long time) through the popup “there is an update”, following this directions;
it downloads the update file, and stores this in the d:\temp -directory and the updates gets stuck, so the browser does not work any more. ((by the way: D:\TEMP is the legitimate temp-directory for the system!!).

The only solution to get the browser to work again (at all and in an updated version) is to manually start the setupfile and choose for upgrade.

chromodo_restart_helper.exe does not start the update of chromodobrowser

Is there any chance you correct this inconvenience/failure?

added info:
Running Windows 7sp1 Ultimate 64b, and chromodo standard installed, as admin and UAC-disabled

Thank you, biteater
