Ascent & Windows User Account Control (UAC)

This FAQ provides an overview of how the Windows User Account Ccontrol (UAC) feature (included in Windows Vista and 7) affects the way you set up and use Ascent.


Can I use Ascent while Windows UAC is enabled?


If Windows UAC is enabled, the following scenarios might apply to you:
• I get an error message that says "Registry access denied".
• I have set up Ascent for the company but my colleagues have completely difference settings, on the same computer.
• I can't see where my Options / Customizations are saved.


Windows UAC is a feature that can help prevent unauthorised changes to your computer. It achieves this by asking you for permission or an administrator password before performing actions that might affect the way your computer functions.

Windows UAC includes a "virtual store" where Windows saves the Applications settings separately for each Windows user. This enables each user to set up and use their software the way they want to, without affecting other users.


You can use Ascent while Windows User Account Control is enabled or disabled.

Ascent with Windows UAC Enabled

Here are the details you need to be aware of when running Ascent while Windows UAC is enabled:
Installing Ascent — Ensure you run the installer as an administrator. To do this, right-click the Ascent installer > Select Run As Administrator. Note that if you do NOT have local administrator permissions, you will be asked for the credentials of a user who does have these permissions. Contact your network administrator for assistance.
Activating your Ascent license - Ensure you run the program as an administrator. To do this, right-click the Ascent icon > Select Run As Administrator.
Using Ascent — No special action is required. Simply double-click the Ascent icon to access the program.
File locations — Because Windows UAC is enabled, all settings and preference files are saved to a hidden folder under the user's folder:

C:\Users\{User Name}\AppData\Local\VirtualStore\Program Files\Commtest\Ascent\.

For Ascent this includes:
Autoview\*.av Custom charts
Backup\*. backup Default backup folder
Settings.ini Ascent User preferences
Settings2.ini Ascent Unit preferences
databases.txt Database opened history
~dataimport.xml Temp file - Last received from vbX Instrument
~dataexport.xml Temp file - Last sent to vbX instrument

To view Hidden folders, open a Windows Explorer window > Select Organize > Folder and Search Options. Select the View tab. Select the Show Hidden Files, Folders, or Drives radio button > Click OK.

Windows Group Policy

In a number of cases, Windows Group Policy may still result in a "run as administrator" message when starting Ascent.  In such cases the following registry change edit may be required.

1. Select Start > type REGEDIT to open the Windows Registry Editor.
2. - 32-Bit Windows - Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\CLLC.
    - 64-bit Windows - Navigate to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\CLLC
3. Right-click the CLLC folder Select Permissions.
4. Select Users and Tick the Allow checkbox for Full control.
5. Click OK - Ascent now functions correctly when you use a non-administrator Windows account.

Disable Windows UAC

Windows users might choose to disable user access control (even though this is not required). Note that if your computer is managed as part of a corporate infrastructure, you might NOT be able to disable Windows UAC.

To disable Windows UAC:

1. Log into Windows as an administrator.
2. Select Start > Control Panel.
3. Select System and Security.
4. Select Change User Account Control settings under the Action Centre area.
5. Drag the slider down to the Never notify option.
6. Click OK — You may be prompted for an administrator password or to confirm your action before this is carried out.
7. Restart your computer.
