Access Violation at Address

The Parts of the Message

The Program Name

When you get this message, Windows will list the program in which the error occurred. The actual executable file for MasterPlan is MPWin.exe, so you will probably see it listed in the error message.

The Address of the Error

Also, if you get an Access Violation message, the address listed in the message may vary from one version of MasterPlan to another. However, you should write down the entire message, because it may be helpful.

Sometimes the address might be something like "Read of Address FFFFFFFF" or "Read of Address 00493F06."

Generally the message will include some more information. We have listed some of the possibilities below:

Additional Information

TAX_CASH_ID" Not Found

This message might also include the following phrase:

ovcIDTax:field

You can get this name if you try to save a Tax and Cash Flow Form without giving it a name. Assign a name and save it again.

Class Not Registered

You can get this message if you have installed or uninstalled a program (other than MasterPlan) that has removed an item from your computer's Registry needed by MasterPlan. Specifically, this message means that the spreadsheet utility in MasterPlan is no longer registered.

We use this spreadsheet utility in the Investment Model Form, the Tax and Cash Flow Form, and in various display windows (such as the Baseline and Proposed What-If Overview Screens) and some worksheet screens (such as the Retirement Needs Analysis and the Disability Needs Worksheet).

Tip: If you can you run a projection report such as the Baseline | Overview without getting this message, and if the Overview spreadsheet shows up (with the Summary, Detailed, Text Report buttons), then that would indicate that the spreadsheet is registered, and we need to look elsewhere.

If you cannot run the Overview report, but you can run the Balance Sheet report, then that would indicate that the spreadsheet utility is no longer registered (i.e. something happened to your Registry).

To correct this problem, you will need to reregister the spreadsheet utility again.

As another solution, you could try reinstalling MasterPlan, but you do not need to reinstall the BDE (Borland Database Engine) or InterBase.

Could Not Access Database File

This will be followed by the name of the database it could not find.

To correct this situation:

You can also get this error if you are using an operating system such as NT, 2000 Professional, or XP Professional. Your System Administrator may not have given you enough administrative rights (such as to create files, to write to files, etc.) for you to be able to access files.

Cannot Create Form. No MDI Forms Currently Active

Again this is an error that can occur on one of MasterPlan's spreadsheet forms. The message will probably tell you the name of the missing file. Make sure it exists on your computer and follow the instructions above to register the file, if necessary. For example, you can get this message if the vcf15.ocx is missing or not registered in the Registry.
