Issue Summary
In Windows, if a document's name do not contain spaces and has a "&" character and the user tries to use the Companion App to edit the document, the Companion App will return an error and will fail to launch. This has been tested on Word documents and documents with the .txt extension but we believe that the behavior is the same across all other document types.
Environment
- Windows
Steps to Reproduce
- Create a word document. Name it a&b.docx
- Upload it to Confluence
- Attempt to Edit the document.
Expected Results
Companion App launches and the document can be edited using the related application.
Actual Results
A "Windows cannot find" the document error is is returned. (see attachment)
In some cases, the companion app just hangs and does not return any error message.
Tested Scenarios:
- a&b will fail
- a&bababa will fail
- a & b will work
- Financial Sample & (test) etc will work
- FinancialSample&(test)etc.xls will fail
Workaround
Change the document's name by removing the "&" character.
[CONFSERVER-57769] Editing a document that has special characters in the document's name fails when using the Companion App.
The issue is not seen as tested locally on Mac on Companion v2.1.0 ( latest ), I mean without using any reverse proxy as I tested on Conf v7.41 and v8.9.4. 
So we need to modify the reverse proxy configuration for Apache & Nginix as mentioned on https://confluence.atlassian.com/confkb/atlassian-companion-app-fails-to-edit-files-with-certain-special-characters-1021222300.html as a solution but as of now, there is no update with IIS reverse proxy configuration.
I'm still having this issue with Atlassian Companion 2.1.0 (and Confluence 7.4.4 (IIS reverse proxy configuration)). When I try to edit attachments containing the '(' and ')' symbols in their filename, I get a "Download Failed, head back to Confluence to try again." error. This issue should probably be re-opened to address this.
Additional reports in CONFSERVER-22403 (it was originally about the Edit in Office feature, but no one closed it after the feature was removed)
Same here, "(" ")" not working. For example "textfile.txt" works fine, "textfile (1).txt" does not.
1.1.0 does not fix this!
However & is working, brackets like ( or ) are causing the Companion tool hangs as described.
Version 1.2.5 of companion.
A fix for this issue is available in Companion 1.1.0. View the Release Notes to see what other issues are resolved.
If Companion is installed via the MSI, then it will need to be manually updated to the new version.
Same issue on Confluence Server 6.13.4. The only difference for us is that instead of receiving an error message, the Companion App just hangs and doesn't open any application.
Same here with + in the filename and as mentioned in the previous comments without the error message from the screenshot but a frozen Companion splash screen inside Confluence.
Hi,
As indicated by Fnet Okuda, it also happens with "(" and ")". In this case the download progress bar remains stucked at 0%.
It happens with Confluence 6.15.2 and Companion App 0.5.3
There are bugs which should be solved as soon as possible (no votes needed), and this one of them.
More pieces of Information
In general, it looks like the problem is with IIS configuration where files that have brackets () are not allowed for some reason while it works with other special characters like $, &&. So the issue is not with the core product ( Companion App or Confluence )
Atlassian Companion 2.1.0 edit testing with special characters mostly brackets () in the file name, browser used Chrome
