I created the following registry keys:

HKLM\SOFTWARE\SHIM1

Name: Version

Type: REG_SZ

Data: 1.0

HKLM\SOFTWARE\SHIM2

Name: Version

Type: REG_SZ

Data: 2.0

Then create a quick SMS Installer package (SHIMVER.EXE) to read SHIM1 Registry Key for Version 1.0.

Check Disk Space


Get Registry Key Value
  Variable=VER
  Key=SOFTWARE\SHIM1
  Value Name=Version

Display Message
  Title English=Version Check
  Text English=Version is %VER%
 

Then ran Application Compatibility Administrator and created the following VirtualRegistry Shim.

Selected VirtualRegistry – Parameter – Command Line: ADDREDIRECT(HKLM\SOFTWARE\SHIM1^HKLM\SOFTWARE\SHIM2)

Now when I run SMS Installer package (SHIMVER.EXE) it reads 2.0
