can't install Solid Edge ST6


Feb 13, 2016
I have installed solid edge ST9 at first and then I wanted to fall back to old release that is ST6 version as i m not familiar with latest and then i downloaded old version that is ST6 and if i try to install it shows an error message that is already another product of solid edge has already been installed uninstall that first and try installing this again. I have uninstalled the latest st9 and did a registry clean deleted all of its files and rebooted and tried everything else possible but i m getting the same error again and again.,.. i m on win10 64bit, the one st9 which i have installed before was worked fine and i have st6 32bit exe installation file and i m trying to install this one. may be that is the reason? any help would be greatly appreciated thank you.
