Revision and Upgrade Information

Upgrade Policy

microEngineering Labs, Inc. offers low cost software upgrades to the latest revision at any time. This page lists the latest version of each of our software products. You need only pay a small shipping and handling fee to receive the latest release. We try to make upgrades available at as low a cost as possible and still stay in business. We do this by using your orginal program disk as both proof-of-purchase and to ensure you receive the proper upgrade.

To receive the latest revision by UPS ground or Priority Mail, send the original program disk with a check or money order for $10.00 and your return shipping address to microEngineering Labs, Inc. at the address at the bottom of the page. Minor changes to the documentation are included on the disk. However, if you would like a new manual for the PicBasic or PicBasic Pro Compiler, include an additional $15.00.

If you wish an alternative method of delivery, or for international orders, please contact us for shipping charges. Please do not request upgrades by email. Our email system gets incredibly bogged down as it is.

There is a special "cross-grade" offer to move from the standard PicBasic Compiler to the PicBasic Pro Compiler: $199.95 plus shipping with proof-of-purchase of PBC. Please contact us or your distributor for more information on this special offer.
