VMWare Workstation - Blank Screen on installation in windows 7


I just spent days to figuring a workaround to this issue. 

Here is what I did:

If you have another version already installed you must uninstall it like this:
  • Go to C:\Windows\Installer
  • Add the "Authors" column and sort by it
  • One of the .msi files with have a "VMware" author
  • Double-click it and follow through with the uninstall steps

Then to install the new version you must extract the installer:
  • Run cmd.exe as administrator with any method... (e.g. type cmd into the search box at the bottom of the start menu and when it shows up right-click on it and select: Run as administrator)
  • Type in "cd the-directory-where-the-install-file-is" then hit enter (e.g. c:\users\bob\downloads\)
  • Type "the-name-of-the-install-file.exe /e tempfolder"
  • Give it a few minutes or so to finish..
  • Go to that new folder (e.g. c:\users\bob\downloads\tempfolder\) and find the .msi file (for VMware Workstation it's named "vmware workstation.msi"), and run it

This worked for me. Good luck.

How to enable debug information over exceptions on SharePoint 2010

SharePoint has always hidden the real error messages and all debug informations relating the same error, to maintain a good relationship with the final user that most often gets scared at the sight of all those written preferring the usual phrase "an error has occourred".


In WSS 3.0/MOSS 2007 to enable that informations we have to modify only the web.config related to your web application.

Instead, in SharePoint 2010, we have to modify two different web.config:
the one that you can find into the root directory of the web application in which you want to debug you customizations (the file at the path: [drive]:\inetpub\wwwroot\wss\virtualdirectories\[port])

the one that you can find into the "LAYOUTS" directory under the SharePoint root (the file at the path: [drive]:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS)

What remains unchanged from the previous version of SharePoint are the number of attribute to change in the web.config file:

The "debug" attribute of the "compilation" element has to be set to "true"

The "callstack" attribute of the "safemode" element has to be set to "true"

The "mode" attribute of the "customerrors" element has to be set to "off"
