Troubleshooting Installation Problems

This section contains some technical notes on problems that can happen during the Install and Uninstall process.

Run As Administrator

The most common problems that happen during the install are caused by permissions problems, this is particularly true with Windows Vista and Windows 7 / 10 / 11. These can be resolved by running the install using Run as Administrator. You may need to do this even if you are signed on with a user with administrator rights.

Known Problems with Installing AQT

The following are a list of problems that users have encountered with the install process, and how these can be resolved.

• Windows NT has a bug that can cause Internal error 2755. 1631. This problem is described in the article http://support.microsoft.com/?kbid=251274 It can be resolved by removing any null values from the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. Use regedit to remove any null values from this registry key.
• The install fails and gives message The wizard was interrupted before Advanced Query Tool could be completely installed. Your system has not been modified. To complete installation at another time, please run setup again. This is a problem with the Windows Installer that Microsoft provide little useful information on. The following workaround has been found by one user.
  • leave the AQT Install dialog open on your desktop. Do not close this.
  • go to your TEMP directory which (depending on your version of Windows), may be C:\Documents and Settings\<username>\Local Settings\Temp. <username> is the name which you are signed onto Window as.
  • in the TEMP directory will be an msi file with a random name such as 533daa.msi. If you hover your mouse over this, the Tooltip with the program properties will display. This will tell you that this is indeed the install file for AQT.
  • double-click this msi file; this should rerun the AQT install which hopefully will work this time.
  • you can now close the original Install Dialog (as per the first step). The temp *.msi file will be removed.
• while installing AQT, or uninstalling a previous release, you get message:
  • error: 1324 The Path My Pictures contains an invalid character or
  • error: 1327 Invalid Drive: x:\

  To resolve these:

  • start Regedit
  • go to registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
  • look at each entry and see if the directory is valid. For instance, it might refer to a network that no longer exists
  • change the entry to refer to a valid directory
• while upgrading or uninstalling, the Windows Installer asks you for the previous aqtxxx.msi file. This only happens in rare circumstances. In this case, you need to supply the aqtxxx.msi file as requested. If you no longer have a copy of this, contact us for it.
• if your AQT installation state is completely corrupted, you can remove the install entries using the Windows Installer CleanUp Utility. This is no longer available from Microsoft but can be obtained from ourselves. It should only be used as a last resort.
• you can get the message error: 1152: Error extracting xxx.msi to a the temporary location. This error is caused by a problem with the Temp directory; it is either full or corrupted

Install Information

Windows keeps information on installed products in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\, followed by the product key. To find the AQT entry, either search through the entries or contact us for the product key.

The uninstall of AQT can fail if this entry has been corrupted.

This entry will give the location of the *.msi file that the Windows Installer uses for the install.

Microsoft .Net Framework problems

AQT v11 uses .Net Framework 4.5. This is a standard part of Windows 7, 10 and 11. No software needs to be installed for this.

We've had a few users for whom the .Net Framework has become corrupted. They see the following error when attempting to signon to a database:

Processing error at do_conn The type initializer for 'Syncfusion.Windows.Forms.Edit.Implementation.Config.Config' threw an exception.

This problem is described in AQT gets error in Syncfusion.Windows.Forms.Edit.Implementation.Config.Config.
