What clients say:

I find XLRotor a unique and powerful rotordynamics software where its ease of use, productivity, Excel interface and automation with its new feature of Singular Value Decomposition analysis make it the BEST of all its kind. Moreover complicated and time consuming analyses can easily and efficiently be carried out in XLRotor within a very short time. The prompt technical support is outstanding. XLRotor is simply a MUST software for every engineer willing to master the rotordynamics field.

Upgrade Policy

XLRotor licenses are perpetual and do not expire. However, periods for Support and Upgrades do expire.

Software upgrades are provided free for all licenses within their active period for Support and Upgrades. One year is included with all new purchases, and is annually renewable thereafter for 15% of the license cost. However, if Support has expired, after a 90 day grace period, the cost to renew will increase by approximately 5% per 6 months to as much as 50%.

When the XLRotor startup box is displayed by Excel, the date when Support and Upgrades expires is displayed in the startup box. Or, in Excel on the XLRotor ribbon tab, click the button for Program Info on the far right of the ribbon.

If you require a legacy version of XLRotor compatible with your key, please send an email to SUPPORT@XLRotor.COM or directly to your XLRotor support engineer.
