Technical Support


As a registered user you may contact us with any questions concerning AvanTax eForms. Although we can resolve most problems over the phone or by email, we may occasionally need to connect to your system or obtain a copy of your database to resolve your problem. We may not be able to resolve a problem if we are not able to access a copy of the database in question.


To send us a copy of your database, select Send E-mail to Technical Support from the Help menu; your default email program will start and the database can be added to your email message as an attachment. The current eForms database is displayed on the Start Page and can also be displayed using the About eForms or Diagnostics and File Locations options of the Help menu.


Confidentiality Statement

Under no circumstances will data submitted to ELM Computer Systems by its clients be used for any purpose other than the resolution of technical problems encountered by the client during the client's use of eForms. Data will neither be disseminated to third parties nor will it be used in any manner not immediately related to the resolution of these technical problems.


Send Error Log

You can also send ELM an error log by selecting Send Error Log to Technical Support from the Help. A log containing the details of any problems encountered during the use of eForms will be sent to our Technical Support staff for evaluation.
