You should use an administrator account to install the application. In some cases, especially when a domain controller is present on the network, you should log on as Administrator to your local PC. If you will run this only once with administrator privileges you should:
- Navigate to the program folder of CutePDF Writer.
- Right-click the program icon (the .exe file).
- Choose Run As Administrator.
- If you see a User Account Control prompt, accept it.
If this doesn't solve your issue you should contact tech support from CutePDF.
