Unfortunately, CS3 is not designed to work with Windows 10. I'm assuming a Windows update has finally put your OS out of spec with CS3. There is really no support from either Adobe or Microsoft on this issue.
You can try direct download installs but there has been a lot of traffic on the forums from people with the same issue and no solutions. Sorry.
I have to ask my computer service man to reinstall Win / on my office computer, there is dozens of computer programs that suddenly stop working. What is the sense of a new Win version if I can not work any longer. I have during more than ten years developed a working environment with many programs that has been working well together. Now my whole workshop is ruined lika after an earth quake. I do not have the money nor the time to build me a new workshop with large investments in programs and equiopment. I have to return to win 7 or close my firm and go fishing in Walden pond. email@example.com
When you upgrade the system you must budget for all new apps. Especially on Mac but more and more on Windows. This can make free upgrades very expensive. Current InDesign is subscription only and includes upgrades, a necessity with systems changing faster than ever. Never cameras and monitors also need upgrades.
To opt out freeze everything and disconnect from the Internet (I like this option). You cannot reliably decide to upgrade just parts.
