Which version of Vista?
There are four versions of Windows Vista; Home Basic, Home Premium, Business and Ultimate. Because we believe most of our customers will want to use the Business version, it is that version on which we have tested Tax Assistant. If there are any issues that our customers come across on other versions we will report them on this page. At present, we recommend that if you are buying a new computer or upgrading your existing machine, you should select the Business version of Vista.

User permissions
It is essential that the location in which Tax Assistant is installed has full access permissions (read and write) for all users.
After installing Tax Assistant on a Vista machine carry out the following procedure before using Tax Assistant.
You must carry out this procedure before creating an Activation Request otherwise you may not be able to activate your licence.
We have assumed here that Tax Assistant has been installed in the default location, which is:
C:\Program Files\Tax Assistant.
Select Start -> Computer to open the Computer window.
Double-click on the C: drive icon to open it.
Double-click on the Program Files icon to open that folder.
Right-click on the Tax Assistant icon and select Properties on the menu to open the Properties window.
Click on the Security tab.
Click on the Edit button.
In the Group or user names list, select Users.
In the Permissions for Users list, tick the Full control checkbox in the Allow column.
Click on the OK button in the Permissions window.
Click on the OK button in the Properties window.

Multiple users
If your computer is set up to have multiple user accounts you may need to activate the Tax Assistant licence separately for each user account. This will require you to carry out the Activation Request,/Activation Key procedure while logged into each user account. Note, however, that your licence is for the computer as a whole and not for individual user accounts.
We expect to eliminate the need for this multiple activation process in the future.

Programs prior to year 2000
Tax Assistant programs prior to year 2000 will not run on a Windows Vista system.
If you want to run the programs for Tax Returns earlier than year 2000 you should install Tax Assistant on a Windows XP, 2000 or 98 system. There are no licence restrictions on these earlier years' programs, so you are permitted to use them without the need to activate a Tax Assistant licence.

TA Online Update
TA Online Update uses a small application called WiseUpdt.exe to check for available updates on the Drummohr web server. This application has the Vista classification Not yet classified and is blocked at startup. You can still run the TA Online Update manually, either from the Tax Assistant Desktop, from the Start menu (select Start -> Tax Assistant Update) or from the Vista notification area (select Blocked startup programs and run WiseUpdt.exe).
We are currently investigating how this limitation can be resolved.

Mouse wheel
There is no direct support for the mouse wheel in the Tax Return programs. In Windows XP, the driver software for a Microsoft Mouse usually enables scrolling on the Tax Return pages using the mouse wheel. It appears that in Vista this is no longer the case. You can, of course, continue to scroll the pages using the vertical scroll bars at the right-hand side of each page and also via the up and down arrow keys.
We are currently investigating how mouse wheel support may be enabled in Vista.
