Windows 7, winhttpwebsocketcompleteupgrade -- error

Hi ​@glenda08854 ,

Hope you are doing well and thanks for reaching out. We are sorry for the trouble you are experiencing.

On the "winhttpwebsocketcompleteupgrade" error: this is a known compatibility issue with Windows 7, not something specific to your install. Here's what's going on: recent versions of Acrobat Reader include a background component called AdobeCollabSync.exe, which handles Adobe's cloud sync and collaboration features. That component tries to use a function called WinHttpWebSocketCompleteUpgrade, which only exists in WINHTTP.dll on Windows 8 and later. Since Windows 7 doesn't have that function, you get the "entry point not found" error at startup. It doesn't actually stop you from viewing PDFs, but it is worth clearing since it pops up every time.

To stop the error from appearing:

1. Open Acrobat Reader.
2. Go to Menu > Preferences > General.
3. Uncheck "Show online storage when saving files" and "Show online storage when opening files."
4. Restart Acrobat Reader.

This prevents AdobeCollabSync.exe from launching, which should stop the error from showing up at startup.

On the second issue, the shared Adobe Scan link giving "We're not able to open this document. It's either corrupted, or the file type isn't supported": a couple of questions to narrow this down:

• Are you opening that shared link on the same Windows 7 computer, or on a different device?
• Which app or browser are you using to open the link?
• Does the file open fine if you open it directly in Adobe Scan or Acrobat, rather than through the shared link?

If the file opens fine locally but not through the shared link, try generating a new share link from Adobe Scan, since links can occasionally go stale or fail to sync properly.

Let us know how the online storage setting works out, and the answers on the shared link issue so we can help further.
