What was the error message?
What did you upgrade?
Re-installed from DVD after PC upgrade XP > W10
Have licence key available, but at entering says "Does not belong to this product type".
XP installation was from download, but CS 5.5 is not available any more, so used DVD from the person who initially started using AI in our organisation but handed over to me.
I think licensed keys are shuffeled somewhere.
Contacted Adobe via Chat, but was re-directed to this forum as the don't support 5.5 any more .....
Sounds like you have mixed a standalone key with a suite package installer, or vice versa, or you have the wrong package downloader for your package key.
We really cannot help with licensing issues on the forum. Try Contact Customer Care
This reminds me of our situation. We had for CS5 different licenses for different uses. Design Standard - Design Premium and Master collection. We stored the master installation package on our installation server for easy access, but we could never install with the lesser keys, which is not logical in my eyes. And I'm conviced that with CS3 this worked. We installed the trial - then entered the key with the first start of Photoshop.
And at the end of our CS5 period, we needed to install the patches mannually for each product.
I think that Adobe did here an unfair job. Even if The products are not supported anymore, as long as there is some key to be entered to get use of the software, Adobe needs to support that operation. If Adobe does not support this anymore, a patched version should be available as with CS2. This said, and in view of all illegal software and patches out there, I understood clearly why Adobe and others try to protect their software and revenue base. As soon as we do money with the tools, we should be able to pay for the tools, to allow for progress and innovation.
Contacted Adobe support, but the directed me to this forum.
As a sw engineer my self, I fully support your statement concerning protection for illegal copies.
But when they stop support for a -1 version and/or as in this case, the original installation CD is available ... that's a different story...
Contact them again, insist they are required to help you and ask to be escalated. Take names. If that doesn't work we'll try to escalate this through back channels to staff here, but you have to do this through Adobe, not the forum.
Correct. Do as Peter says.
