DotNet35FWWrapper error during upload or download - "Arithmetic operation resulted in overflow"

1. Go to Control Panel and select Programs and Features. Select 'Turn Windows features on or off". Make sure Microsoft .NET Framework 3.5.1 is checked. Click the plus-sign to the left of that option to expand the section and make sure both options underneath it are also checked. 2. Re-register the .dll files - bring up the CMD prompt as an Administrator. One at a time, paste the commands below at the prompt then press Enter: C:\AS\regasm /codebase /TLB C:\AS\DotNet35FWWrapper.dll regsvr32 C:\AS\MSXml4.DLL regsvr32 C:\AS\ASWMessenger.dll 3. Reboot the laptop. 4. If the error still comes up when you attempt an upload or download, see if it is coming up at the step where it is trying to download the Master Option File. If it is, replace all 4 files beginning with ASMstrOP in the rep's CARS folder with the copies from your own CARS folder. Relaunch AutoStik and try the upload/download again.
