I submitted a ticket with this error .portable rewire dll.cpp(895) and was resolved with the following steps thanks to tech support.

Windows comes with a hidden administrator account which must first be enabled.  To do so:
1. Type  "Command Prompt" into Windows search or Cortana 
 2. right-click on the Command Prompt result that appears and choose  "Run as administrator" 
3. After the command prompt opens, type:   net user administrator /active:yes
4. Double check to make sure the command is entered correctly and hit Enter on your keyboard.
5. After running this command, the prompt will respond with:  command completed successfully

6. Go back to the Windows desktop , and click your user name in the upper right hand corner and select Administrator from the drop down options.
7. Install and activate your former Sony Creative Software applications onto this profile.

FOR STEPS 6 & 7 i just skipped both.

I selected the Acid.exe file (right click, properties, advanced and select RUN AS ADMINISTRATOR. This solved my situation.
