Hi,
the latest update from 25.04.2017 stuck at 83,8% for hours on one of my PCs 3 other ones got it without any problems.
Any help would be appreciated to avoid using a full backup from last month
best regards

One user had found two instances of cmdinstall.exe running and they had killed the one using less memory to get it to work. However you can follow this guide to make sure you have a correct install.
Memory shouldn’t be a Problem on a Win7 64bit machine with 64Gb Ram 
Will have a look at your link later thx for your reply and your hint!
