Upgrade Policy

microEngineering Labs, Inc. offers low cost software upgrades to the latest revision at any time.  If you purchased software from one of our distributors, we recommend that you contact the same distributor to purchase the upgrade.   

Qualification for upgrades: You are entitled to purchase an upgrade if you purchased the original software from microEngineering Labs or one of our authorized distributors. Our software licenses are not transferable.  This means that if you purchase a used copy of our software from an individual, you are not entitled to an upgrade.  If you purchase our software on EBAY or a similar auction site, make sure the seller is an authorized distributor of our products.  You may check our distributor list to verify a seller. When you order an upgrade, we will search our database for a record of the original purchase.  If a record cannot be found, this usually means that you purchased from a distributor.  You will be asked to provide a copy of the original invoice as proof of purchase.

Purchasing Upgrades:

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.

Online ordering for upgrades is now available.  You may need to fax proof of purchase to qualify.  Upgrade disks will be shipped to you.  There are no downloads available.

Ordering by mail: United States: Use our order form to create documentation.  Print the completed form and include it with your payment and proof of purchase.  Make sure that your return address, telephone number, and email address are correct on the form.  This helps to avoid delays caused by incomplete or unclear information.  Credit card orders may be faxed.  Shipping cost will be calculated based on the method you choose on the form. Outside the United States: If you purchased software from one of our distributors, we recommend that you contact the same distributor to purchase the upgrade.  If this is not possible, use our order form to calculate shipping costs and generate documentation.  Print the completed form and include it with your payment and proof of purchase.  Make sure that your return address, telephone number, and email address are correct on the form.  Credit card orders may be faxed.
