• When trying to upload an APK app to the XMS console using Internet Explorer 11, we are getting a 500 Server Internal Error Looking into the error logs.
• The previous version (x.x.x.0) works fine however upgrading the version gives -
  500 Server Internal Error (exid:15F529099BB-54F45A1D0DDB4C1CF5B18A0FF04C1CB5)

On the debug server logs, we see lots of Java errors where the server is trying to manipulate the APK file, but for some reason the upload is eventually failing.

• Added XMS URL to the Internet Explorer compatibility list (see Fix site display issues with Compatibility View in Internet Explorer 11) to XMS fixed the issue. Additionally, using another browser would have fixed the issue, as this couldn't be reproduced using Chrome or Firefox.
• If this doesn't resolve, fix is included in XMS 10.7 RP2 , updated with new version of apk tool to unpack apk files - https://support.citrix.com/article/CTX230553

Problem Cause

• IE11 seems to have problems when uploading some APK files to XMS.
• The apk-tool version used for XenMobile10.7.0.20.
