The issue is occurs due the CustomBridge.dll is loaded in
the .Net 2 CLR. When this assembly tries to load your .Net 4 assemblies it
fails since it is trying to load a .Net 4 assembly in the .Net 2 CLR. Due to
this the QTP doesn’t play back for 4.0 frame work application. We can resolve
this issue using the following workaround. Please follow the following steps.
Step 1:
Please download the
new QtComFactoryU.dll from the below link and replace the old QtComFactoryU.dll
in the HP QTP installation location “<install
location>HP/Quick Test Profession/bin”
with the new QtComFactoryU.dll.

Step 2:
Open the registry
and search the string “QtComFactoryU.dll “.You can find the 5 distinct keys
with this string.
Step 3:
For each such key,
we need to modify the “RuntimeVersion” value. Right click on “RuntimeVersion”.
Then click the modify option and replace the existing “v1.1.4322” with the
string “v4.0.30319”.
Step 4:
Now close all QTP related application properly and restart the system and now run the HP QTP. Now you can
able to record and play back the 4.0 frame work application in HP QTP 11.
