XenDesktop 7.5 mapped drive execute permission

By default it’s not possible to run executables (install software) from a client drive which has been mapped to a XenDesktop VM. A work around is to copy the files to a network share and run the installation from there, but it takes time and can be a fair bit of extra work.

Instead, it’s possible to enable execute permissions via a quick and simple registry modification on the VDA (the XenDesktop VM). No DDC or client PC changes are required.

  1. Start “regedit”
  2. Navigate to “HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\GroupPolicy\Defaults\”
  3. Add the key “CDMSettings”
  4. Add the following DWORD value: “ExecuteFromMappedDrive”
  5. Set “ExecuteFromMappedDrive” to “1”

A restart of the VM is required for the changes to take effect.

Tested on XenServer 6.2 with XenDesktop 7.5 on a Dell R720 with NVIDIA K2 GPU card (K240Q and K260Q vGPUs assigned to the VMs).
