If you are still having issues, Try this it workd for me:
- Follow the process as per ThumperTM's post.
- Open Control Panel
- Select "Programs and Features"
- From the list find "Camtasia 9" and right click and select "Change"
- Then select "Repair"
- Once done recopy the "RegInfo.ini" file over with the chances as per ThumperTM's post
After copying the cracked RegInfo.ini file to the "C:\ProgramData\TechSmith\Camtasia Studio 9" folder, right-click to edit it with notepad and substitute the info inside for this info:
[RegistrationInfo]
ValidationData3=1
RegistrationKey=UVVDD-MJCCC-CD9MC-3KCBQ-293CF
RegisteredTo=ThumperTM
ValidationData1=
ValidationData2=1
Save, right-click the file, choose Properties, and mark it as READ-ONLY.
Open Camtasia and you should be good to go....
