Parallels tools installation hangs at 62-67%

Yosemite 10.10.3
Parallels 10.2.0 (28956)
Windows 8.1

Everything worked great before last Parallels update. Parallels updated but did not complete Parallels Tools installation. Have tried various things suggested in forum. Installation still hangs at 62 or 67%. While it is installing the Windows screen flashes a couple of times from the Windows desktop to the initial login screen.
Any help is appreciated!

Hi @NancyL, please try this solution

 

Maria, thanks but that apparently does not apply to my system. I did find under Windows Devices it shows IMAC-WINDOWS with a yellow exclamation point noting that it needs attention & says that the driver is unavailable.

 

Hi Nancy,

OS X 10.11.1
Parallels Desktop Pro 11.0.2 (31348)
Windows 10 Pro
I had a similar problem with a Parallels Desktop 10.x update (10.2 to 10.3) and now again installing Parallels Tools after upgrading to Parallels Desktop 11 Pro. In both cases I could solve the problem in this way:
- uninstall previous version of Parallels Tools from Control Panel if possible (in my case I also got errors during uninstall)
- reboot the virtual machine
- delete the folder C:\Program Files (x86)\Common Files\Parallels
- delete the folder C:\Program Files (x86)\Parallels
- delete the folder C:\Users\<UserName>\AppData\Roaming\Parallels
- delete the content of C:\Users\<UserName>\AppData\Local\Temp
- delete the content of C:\WINDOWS\TEMP
- delete the registry key HKEY_CURRENT_USER\SOFTWARE\Parallels
- delete the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Parallels
- delete the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Parallels
- find and delete any "oemXX.inf" (and related "oemXX.pnf") file in C:\WINDOWS\inf containing information about Parallels Tools or Parallels software
- reboot the virtual machine
- disable anti-virus software (just in case...)
- install Parallels Tools

Hope it can help.

 

I've had the same problem on my Windows 7 install ever since the last 2 updates. Mine gets stuck at the same point. I haven't been able to fix it and am stuck with a partially functioning system unable to use coherence.

 

Hi @Blahman, try doing a manual installation. Refer to this article.

 

Yes, I've tried that. The problem is that mine is a work setup that I don't have admin privileges for, and my IT department has refused to help because they don't support Macs.

All I can do is either revert to an old snapshot and hope it installs correctly automatically (which doesn't work- it hangs at 67%), or hope you guys can work out and fix why it hangs at 67% by the time of the next update.
