Q]  "Customers using Avast antivirus software experiencing problems running IApproach"

A).  Problems can occur when Avast antivirus falsely identifies IApproach as a virus.

This is known as a "False Positive" and can occur at any time when your antivirus definitions are updated.
  1. 1). Please read the Tdata bulletin regarding Avast antivirus (Avast bulletin).
  2. 2). These instructions show you how to add IApproach to the exceptions list so that you can eliminate the problem.

Q] "When printing an FAA form, all of the checkboxes are checked (for example 337 in Block 4)."

A).  This can occur if you do not have Adobe Reader installed or Adobe Reader is not set as the default for viewing PDF files.

Many new computers come with Microsoft Reader and no Adobe Reader. Also, older computers sometimes inadvertently download a third party PDF Reader that “overpowers” Adobe Reader and becomes your new default PDF reader.
  1. 1). Check your list of programs. If you do not have Adobe Reader, go to www.adobe.com and download the latest free version. It should become the default automatically. You can confirm this by following the instructions below.
  2. 2). If you have Adobe Reader and want it to be the default program for PDF files, find a PDF document and right-click on it.
  3. 3). Select “Open with” and choose Adobe Reader. Be sure the checkbox labeled, “Always use the selected program to open this kind of file” has a checkmark in it. This will set Adobe Reader as your default for PDF documents.
  4. 4). If you need help with this procedure, please call Tdata support at 614.885.1169 or contact us

Q] "ERROR 4401 or Trouble viewing SBs, TCDS, ACs or FARs"

A).  CAUSE: Recent changes with Internet Explorer 9 have restricted portions of the registry which were previously available. 
  1. 1). To correct this, save this file to your desktop IApproach_Fix.zip
  2. 2). Unzip the file 'IApproach_Fix.reg'
  3. 3). Right-click on 'IApproach_Fix.reg' and choose 'Merge'
  4. 4). Allow the file to merge into your registry then restart IApproach.
  5. 5). * If you need help with this procedure, please call Tdata support at 800.783.2827 or email support

Q] "I am having a lot of error messages which cause the program to close or my computer to lock up."

A).  The most common causes include: 
  1. 1). A dirty or defective CD-Rom drive
  2. 2). Scratched, defective or dirty CD media
  3. 3). An outdated CD-Rom drive (manufactured around 1997 or before)


Even if your drive can read other CDs without problems, please remember that Tdata's CD contains a lot of data and therefore your CD-Rom drive must be able to read to the outer portion of the media. One of the following will fix the problem. 
  1. 4). Obtain a CD-Rom cleaning kit (available at your local computer store for about $10) and clean your CD-Rom drive. Your drive contains sensitive optics and cleaning it will remove dust which can cause problems or degrade your drive's performance.
  2. 5). Examine the back side of the CD media for scratches or smudges. If the media is dirty, try cleaning it with a soft cotton cloth.
  3. 6). Try a previous issue of the Tdata CD and see if you have similar problems. If so, this may indicate that there are problems with your CD-Rom drive.
  4. 7). Try the media in another computer (if available) and see if you can look at the contents using Windows explorer (you do not have to install IApproach to examine the disc this way).
  5. 8). If you feel that the CD media is defective, please call us to obtain a replacement. [ 800.783.2827 or 614.885.1169 ]
  6. 9). Replace your CD-Rom drive with a new one.

Q] "system error 31" or similar message - Windows ME users only.

A).  If you upgraded from Windows 98 to Windows ME, Microsoft has acknowledged that problems exist with MDAC (Microsoft Data Access Components) being installed. MDAC must be in place before IApproach can be installed. Microsoft has issued the following description and workaround to the problem: Microsoft issue and resolution: (Note: This is for advanced Windows users only. Please contact Tdata Technical support if you need help with this procedure.) The error can occur when the ODBC drivers are damaged or corrupt or a mismatched version of MDAC is installed. Since you have Windows ME installed, the new feature "System File Protection" of Windows ME will prevent you to update MDAC. System File Protection (SFP) is a feature implemented in Windows ME that ensures files critical to system operation are not replaced by older versions or versions not approved by Microsoft. If a product, including Microsoft products, attempts to replace a Windows Millennium protected file with an older version of a protected file, the files will be replaced with the protected files automatically and silently. To install the MDAC 2.6 (or MDAC 2.5 SP1) successfully, you may try the following steps: 1. Make a bootable disk. 2. Reboot the system from the floppy disk so that you can start up in DOS mode. 3. Rename (do not delete) the following files located in the c:\windows\system directory on your PC to *.old: ODBC32.dll and ODBCJT32.dll Note: the files are located in the System directory. Please write down the file version before renaming and check the new file version after you install MDAC. Thus, you can make sure whether or not the old files are replaced by the new ones when you install MDAC 2.6 or MDAC 2.5 SP1. 4. Rename (do not delete) the following files located in the c:\windows directory on your PC to *.old: ODBC.ini, ODBCINST.ini 5. Reboot the system to Normal mode, and install MDAC. Check if MDAC is installed correctly. 6. Reinstall IApproach and try running the program. If you need assistance, please contact us at 800.783.2827 or 614.885.1169 or [email protected] 

Q] When I click on Summary of STC's and I get an hour glass and then it goes away and nothing happens
