Hello!
I have x64 based processor and currently I am using 32 bit OS of windows10.
I have recently upgraded my RAM from 2GB to 10 GB out of which only 3.4GB is usable because i am running in 32 bit OS.
Hence, I need to upgrade it to 64 bit OS.
But the problem starts here, whenever I run the installation file, Error code 0x8007007E-0x90018 pops up in my screen , whenever I tries to upgrade windows 10 from 32 bit to 64 bit.
Kindly help me in solving this error . so that i can upgrade my pc to use my full ram and run my pc smoothly.
Thankyou!

Do I understand correctly that you want to upgrade from 32 bit to 64 bit as an in-place upgrade? That will not do.
A change from 32 bit to 64 bit is only possible with a clean reinstallation.
Friendly greetings

Error code 0x8007007E means ERROR_MOD_NOT_FOUND - The specified module could not be found.
I hear for the first time that the error occurs during a clean Installation. You boot from the USB stick for the clean installation?
Please explain in more detail at which point this error occurs.
Friendly greetings

An in-place upgrade of 32 bit windows to 64 bit is not possible to do. You'll need to clean install the operating system.

Hi,There is no in-place upgrade path to make the switch from 32 bit to 64 bit, making a clean installation of Windows 10 the only viable option.
