That sounds like a driver issue, and there shouldn't be any reason to uninstall 365. I have PD13, 14, 17 and 365 installed on my desktop, for example. Make sure you have the latest video driver installed, and maybe force a clean driver installation and run the system check commands as described in this post.

Also, no reason to set the compatibility mode to anything as Win10 was in use when PD17 came out.

Maybe try uninstalling PD17 then installing it as an Admin (right click on the installer and choose that option). You may also have a corrupted user account, and creating a new test account will let you see if that's the issue.

Thanks optodata;
I did everything you suggested with no satisfaction. I did send a request to Cyberlink support telling them everything I have tried (including what you suggested). Hopefully they can sort it out.

I think that's the best option at this point. Please post back with the solution if they're able to get you up and running again!

bjtap1,

Title appears to indicate issue upon starting PD17 but post body appears to address installation of PD17. If installation, I serious doubt any drivers at play for that issue.

I assume you are installing from your original downloaded files that are similar to CyberLinkPowerDirectorUltimate17_0xxxxxxx.part1.exe and associated other ****.partX.rar files? Do you have all the parts? If that's the case, I'd probably look at your anti-virus software since you indicate the installation crashes immediately.

Thaks for replying. This does not appear to be an instalation problem as it appears to install well.
Cyberlink has sent me an url to redownload version 17 with all the accomying files so I am in the process now of downloading and reinstalling. Hopefully that will rememdy the situation. I will post back here the reults.

Make sure you have patched to at least 2727 after your install. That patch had a critical fix to correct a crash that occurs on application launch. Hopefully CL provided current release install files. My confusing was OP wording, "Upon starting the PD17 installation (in any mode) the program crashes." I assumed installation meant starting the PD17 installation, not simply launching the installed application.

Solution???
After having no luck reinstalling with the new download files support told me it was a newblue .dll file and suggest I delete all newbluje file and reinstall PD17. I did that and still the same problem.
My 'solution'. I reinstalled windows 10. That seems to have 'solved' the problem.
Thanks to those who chimed in here.
