Im using a 32 bit Vers, and cannot install 64 bit version, help

[yaliars]

i cant boot either from cd or USB(Disk on key), it skips the booting and starts regular windows. Yes, ive changed the bios settings to first boot from dvd/cd and USBs but it still doesnt work. Ive tried to open the installation inside windows and i ve had an error saying the the file version(the file is setup.exe which ive double clicked) isnt compatible with the version of the windows im running, and that i need to figure out what OS fits to my PC, 32 or 64 bit. btw i checked my pc with windows 7 upgrade advisor and i found out i actually CAN run a 64 bit windows on my system. i have both dvd and usb with the installation files but i just cant reach the installation in any way. please help me, thanks.

Hi yaliars, welcome to the forums

Within Windows try to right-click the setup.exe file and select (under the compatibility tab) compatibility for Vista [any SP]. Click ok then try running again.


OS

Still got the same error, tried all kinds of vista compatibilities

Where did you get the x64 install media? Is it in fact bootable? How did you create the USB thumbdrive? It has to be done a certain way to make it bootable.

Heres what ive done: with the software UltraISO ive clicked the section bootable then write disk image, with the windows 7 ult 64bit.iso, ive set the write method to usb-hdd+ and press write. if im wrong and theres another way please tell me how. btw even if i try to run setup.exe in my current windows and not as a boot installation it doesnt let me and send me the error ive described earlier. please help me im trying to switch my OS for like 10 hours already...

Where did you get the ISO file from? If it was a reputable source just burning the ISO file should create a bootable DVD. Also this utility > Microsoft Store: Windows 7 USB/DVD Download Tool Help < should create a bootable USB thumbdrive from the ISO file suitable for installing windows 7. That is assuming the ISO file was created from an original bootable DVD.

UltraISO always works for me but only if the iSO is sound. Where did you get it? Check it's HASH using Hashtab against the official Win7 Hash: Windows 7 RTM SHA-1 hash / checksums

You can't run 64 bit intaller from Windows 32 bit at all. Gotta boot it, as you seem to know.

Remove all but 2gb of RAM to try install. Test your RAM with memtest86 CD for 5-6 passes or overnight.
