Good job, there, Mel on calling Dell. Did you ask them point blank
about the W10-->W7 downgrade OS issue? Did the OptiPlex support that? If the Hardware doesn't support the OS downgrade to W7; you are fighting a losing battle I'm afraid.
As of Aug. 2nd 2016, last month, Microsoft announced plans to change the kernel of W10 to work with new hardware improvements by the PC manufacturers such as Dell, Acer, HP, Asus, Toshiba, etc. This also means, that if your PC is brand new; built in 2015-2016, it may not be downgradeable from W10 AU update (came out Aug. 2nd) v1607 version either. That means that if your PC has W10
v1607 b14393.187, and you attempt to downgrade to W7 or even W8/8.1 that probably won't work.
Your PC seems to have been built between 2014 and 2015. You can determine the exact Build date from the Dell sticker on the back of the Tower case or on the bottom of the case where the rubber feet are. (sometimes on older Dells, they put the Service Tag sticker on the top of the Case. In most cases, it will be a Black Sticker with silver or white lettering on it.
Prior to contacting your software vendor, Profitline (if they are still in business), you should determine exactly what version of W10 you have installed on that OptiPlex PC. To do this, click on the Start button on W10 desktop, and then hit the
<winlogo-key> + <R-key> simultaneously. This will bring up the
RUN box. Next, type in the command
<winver> without the
"greater than" or
"less than" brackets into the
RUN box. It will return a W10 information box with the W10 version number and OS build number as here:
Report back exactly what your W10 version and OS Build number is on your OptiPlex PC (shown in the
Red Box).
This will help us to help you better. And it will be very useful if you call the Profitline support people or the Dell pay-per-incident software team. They will ask you to do this also, so it will save you some time (and money!).
Lastly, I agree with Dell, that if the Profitline software is so old that it was using Framework 1.1, that software is at least 10 years old maybe more, and that's very unlikely to be able to upgraded. If Profitline is still in business and you call them, most certainly they will tell you there is no upgrade if they do make a newer version for W7 or W10 and if they do it's so old they won't give you a discounted upgrade price; rather they will want to charge you full boat for the newer version. Since I'm not familiar with that software,
could you tell us what it's purpose is? Perhaps one of us can tell you a software that could do the same thing that would be a replacement.
Thanks,
