CID portable problem

I was having some audio stuttering issues with CID V48 installed on my C: drive, so I copied CID portable V40 to a USB thumb drive and installed it so I could run a clean version with no extensions or addone - but when I click on the CID .exe file on the thumb drive my computer loads the C: drive V48 instead - how is that even possible? Do I need to add a command switch to the link for CID portable? There’s no user profile in that directory either - is that possibly the problem, and how to I fix it?
