the problem is probably not with your OS, it is either something wrong with the file or something wrong with the method that Electrum uses while reading that file in that other OS.

try opening that file with a text editor. you should see something like this:

first see if you see any additional lines in this file. then please report back.

as a workaround you can simply copy the "hex" part (the 0100.... thing) and use "Tools > Load Transaction > From Text" this time and paste the copied raw tx there and click Load.

Then try with a different version on both OS - 2.8.3 for example.

Even better, select a version on Github, and compile it on each OS, without relying on the provided binaries.

I suspect that you have less than half a bitcoin in your wallet for you to use such a convoluted and archaic system (who is using cold storage, or paper wallets nowadays...).  If you have more than $1000 worth of bitcoin, why don't you use a hardware wallet (Trezor, Ledger, KeepKey), like the rest of the world?
