Again a copy from my blog - just to let you know, that problem may be there....
I did updates of VASmalltalk 8.02 on my two W7/64 machines. Actually the update seemed to have installed all stuff needed – but both: the client and the manager update (on both machines) ended with that typical error dialog, that Windows asked me, if the product has been updated/installed with success or if the installation should be done again.
The first machine was a W7/64 Home with a limited user account, the second machine was a W7/64 Professional with an admin-rights enabled account.
