GII. Command
Get Installation Information
Intention
This command can be used to get the Uninstall-String for a specified application.
To find out if the application is installed, use IAI. See IAI. for more details.
It will retrieve the complete Application name or the requested uninstall information, if they are available.
The following Script will retrieve the "modify String" of the MS Framework with the given Version-Number:
GII.Micro&ANDTHEN:30729|m
DMP.6
ENR.
This is the result on the Stack:
If we try this (note the "|s" at the end:
GII.Micro&ANDTHEN:30729|s
DMP.6
the the stack will be empty, because there is no silent Uninstallation for this patch.
We can use a variable instead of the stack.
GII.Micro&ANDTHEN:30729|$$RES|u
DBP.$$RES
ENR.
Andthe result is:
while the uninstall string itself will be on the stack.
The command works transparently with both x32 and x64 applications.
Standard-Search Pattern can be used.

Remarks
The command works transparently with both x32 and x64 applications.
Technically the command reads the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
to get these information.
IAI. as well as GII. as well as "InstaRec" build the Name of the Program using a Combination of the "DisplayName" and the "DisplayVersion" Properties. Therefore you can more easily separate which Software you want to deal with.
Limitations:
This command looks for standard information details at:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
If the application being tested for installation did not register this information, the command will not be able to retrieve installation information.
