AQT errors after applying Windows 10 Update 1803

After applying Windows 10 Update 1803, some AQT users may get a number of error messages "Processing Error at Get_Setting. Requested registry access is not allowed".

This only affects 32-bit AQT. 64-bit AQT is unaffected. It can affect all versions of AQT.

It seems that, after update 1803 has been applied, for some users AQT is denied access to the LOCAL_MACHINE part of the registry. AQT doesn't really use this part of the registry, but reads settings from there in case the user has loaded some system-wide settings into this.

AQT functioning is largely unaffected by this problem. The error messages can be ignored.

There are several fixes for this problem. Any one of these will work:

  • (best option) go to the AQT install directory (eg. C:\Program Files (x86)\Advanced Query Tool v10\), right-click aqtv10.exe, select Properties, go to the Compatibility tab and for "Run this program in compatibility mode for" select either Windows 7 or Windows 8
  • (not recommended) repeat the above procedure, but on the Compatibility tab select "Run this program as an administrator"
  • install the latest build, AQT v10.0.5j. This is available on our download page in the section Latest Builds (near the bottom).
