Yes I do have Dreamweaver installed, but I reassigned the .js extension to its normal behavior using a .reg file that I found in another topic. It seems to me like this error occurs during the execution of the .js script.
I also have the same problem. I have dremweaver installed. I have changed the .js extension back to jscript.exe or Windows Scripting host application and it still gives me the same message. I also tried to manually install SQLEXR and the M-PC install still doesn't work. I get the exact same popup message that PolySim gets... Help would be appreciated!
