Error half way installation pdfcreator 0_9_9

After un installing the former version (after telling me that an update is available) I went on installing version 0.9.9. Half way the installation procedure I did get the message (partially transalted from Dutch):
 

C:\\Windows\\system32\\pdfcmnnt.dll An error occured while trying to replace the existing file: DeleteFile failed; code 5 Access denied.

Please can anyone tell me what I have to do now? Thanks in advance, Pieter

 

 Try first to unistall the older version. To do this maybe you will need to download a software call Revo unistaller. After you unistall the older version download again the newer version of pdf creator and installed on your pc. This should work.

 

Best luck.

 I had this problem too... My problem stemmed from having a partially completed uninstall...

I told it to ignore the file and let it complete the install.

Then I told it to uninstall again.

Then told it to install again.

All fine now!
