RESOLUTION
To upgrade the SoftGrid Client, use one of the following methods.

msiexec.exe /i &quot;softgrid-xx-setup.msi&quot; REINSTALL=ALL REINSTALLMODE=vomus

Note You must type either TS for Terminal Services client or WD for Windows Desktops client instead of the &quot;xx&quot; in the command example.

Method 2
Double-click the softgrid-xx-setup.exe file to upgrade the SoftGrid Client manually.

Method 3
Double-click the .msp file to upgrade the SoftGrid Client manually. Or use command-line parameters to execute the .msp file. For example, run the following command at a command prompt:

msiexec.exe /p &quot;softgrid-xx-HFxxxxxxxxxx.msp&quot; REINSTALL=ALL REINSTALLMODE=omus /qn

Note You must type either TS for Terminal Services client or WD for Windows Desktops client instead of the &quot;xx&quot; in the command example.
