EDIT: Resolved my issue. The adobe_prtk.exe file available to me on LWS is a 500kb file. I downloaded the file from here instead -- a 2MB file -- and it worked.
I am attempting to resolve this same issue in our environment using the provisioning tool. However, every time I use the syntax suggested in this thread, I get a return code = 1.
/*location of adobe_prk*/adobe_prtk.exe --tool=Serialize --leid=*LEID* --serial=*Serial* --adobeid=*adobeID*
I've tried other tools/methods to serialize/unserialize/reserialize/generate prov file, etc and I get a return code = 1 for everything. Which leads me to believe I'm doing it wrong. 
I couldn't find the provisioning tool available locally as a result of the CCP install, so I downloaded the tool from the LWS and copied it to the root directory on the client machine. Should I be running the provisioning tool from another location, instead? Any other insight?
