Glad you found the solution. I am in the same boat.
Updating Windows10 32 bit to Window10 64 bit
I am using this forum to do a bit of ‘whining’
With dozens of programs - one over 25 years old which is still used regularly - installed on my systems (I have two) upgrading to Windows 10 64 bit is daunting to say the least. Some of the programs I use frequently others are specialty applications that only get pulled out occasionally. The first step is to format the drive and start fresh.
All of my data files are safely on other drives so data loss is not a concern. It is reinstalling all of those programs (50+ at last count). Some of which have unique requirements. Add to that updating the options within the programs because they all load their default settings.
My solution - which I am just starting - was to purchase a spare computer for the installation of the new OS. Then install all those applications and verify they work. Any data that is stored on the local drive C: is also brought over. Examples of this are web browser bookmarks and all the e-mail associated messages and folders.
Once the new installation is verified I back it up and transfer it to my current systems. Hopefully the new OS will be activated on the different hardware. I have the COA’s for the OS’s.
I can take my time and hopefully I have all the unique steps documented.
Once I get one done then I get to do it all over again on system 2.
What fun !
