Version 12.1.0 (41489) permanent installation of Parallels Tools

Hi, today I was asked to update Parallels Desktop 12 which also required an update of Parallels Tools. I use several Windows 7 virtual machines. As far as I tried all show the same behavior: after startup and login Parallels Tools are installed and at about 40% the system crashes. I tried both ways that are described in two articles concerning that behaviour, none worked. Windows 7 can be run in save mode which shows that the recurring installation of the Parallels Tools is for sure the cause. I have tried that several times with always the same results. Can anybody advice what to do next???

I have the same problem. It crashes after updating 3%. the problem is that I cannot seem to get into control panel in order to remove Parallel Tools ... it just crashes. any other suggestions? I am a first time parallels user ... and just purchased/downladed windows 10 home, although the issue doesn't seem to be with Windows.

 

same problem. It crashes at 51%.

 

I check the log file: C:\Windows\Temp\parallels-setup.log, it says:
INSTALLMESSAGE_ERROR: Failed to install driver prl_time
how can I fix this?

 

me too, it crashes at 69%.

 

Updated Parallels today as I got a popup saying there was an update.... it crashed somewhat halfway and gave me a critical error message at that vm wasn't running or did not start. So I booted up again, windows says system has crashed, selected normal startup, it then did a check disc checkup and I saw messages concerning parallels tools files came up during the process as something was damaged with them... finished the process and booted windows up fine right after.

But like 1 min later, it crashes again... and will do so repeatedly for every next boot.

So thinking I could just get a backup from 1 hour ago from time machine of the image file it would be back and running ok. Same thing happened. So then I uninstalled parallels, downloaded the setup file, did a clean install. Got from time machine a backup further back (about 12 hours back)....

NOW IT DOESN'T EVEN BOOT!

In MSDOS (initial black screen) says that it can not boot from drive or file is missing.

I am panicking right now. All my professional work is on this VM and the backup doesn't even work. Loosing a lot of money by the minute !!!

 

Just did a full backup restore to a backup that TM made 30min before the update occurred. Now it works like a charm. What a life saver.

 

Anyone updated to the latest 12.1.1 with the fix for Windows 7 ? Does it work properly now?
