Have to install TP9 before TP10

[Nick Payne]

When trying to install TP10 as a fresh install rather than an upgrade, my license isn't accepted as valid.

When TP10 was released my TP9 license continued to be valid for it (as per the release notes at http://www.cerious.com/release_notes10.shtml). However, after installing the latest 4007 build of TP10 as a fresh install on a rebuilt machine, when I attempted to enter my license name and code from TP9, I got the response "Code does not validate". I had to uninstall TP10, install TP9, enter the license there,  then install TP10 again, and then uninstall the no longer needed TP9.

Do I need a new license key in order to be able to install TP10 from scratch.

Well, further investigation shows that the problem is with build 4007. Uninstalled it and then installed build 4004, and that accepted the license key ok, after which I upgraded to 4007 and the license information was retained.

That is not my experience. I recently recovered from a hard drive crash, and my rebuild of Windows 7 and ThumbsPlus build 4007 went without a hitch. There might be another, unknown problem preventing the install on your system -- perhaps something in your registry.

Or some difference between Windows 7 and Windows 10... The problem happened on both my laptop and desktop, which both run Win10.

I just made a clean install of Win10, so I had to made a fresh install TP10-4007.
I confirm that it is not possible to enter the registration code.

I made a TP9 install also.
