Thank you very much Claudio and Pat .. 

I will uninstall the 10.1 version

(I hope there is no further complication by trying it manually, erase directly at programs file if adobe doesn't offer a direct means, control panel doesn't work)

And then try 8.3 and 9.5, one by one.

Are there any bugs I should take into account for 8.3 or 9.5, or should I consider just the issue of memory?

Well thank you very much to both of you.

Pat thank You very much again

When I try to use "add/remove" programms .. the Xp system fills with bugs till I have to use  the " safe mode" to retrieve former state of windows... why? I bought a computer without a WsXP CD ... for lacking that  and refusing to place the old CD  the app -which if had I couldn't use anyway because de driver physically burns de CD hhaaahaa- ... when required to remove through the control panel ...  for not being able to prove that such an old Ws version is original  ... I can not use such control panel .. so I try to do it manually by then asking wich registers to erase also hihi .. so

That's why a dared to bader you again asking you about the differences between 8.3 and 9.5 ..

Pitty there is no uninstall through adobe.

I Thank for your time Pat.

Dear trators ..

I made a change of username Deterg to Artra Ata ...now I can'not reply because of that?  "your are not allowed ... " legend.

Is it possible to fix that  ?

Thank you.

Thank you a lot for the address of the Ws fixer ... I have now the 8 AdobeR version.

The bugs ... Pat were a lot of reated dlls for the setup of Ws ... that exhausted the memory ... it happened once and never tried again neither the control panel neither accepting de Ws updates.

all fixed now..

Ultrathanks for everyting Pat... my old PC greatly acknowledges your help

Best Regards.
