Relevant Q&A: 

What if products of LeoKrut are not working at your computer properly?

There could be variety of reasons. We are working hard to ensure best possible performance.
One of the possible situation could relate to the UAC (User Account Control) and othe security services of Windows Operating System at your computer.
The first step to troubleshoot malfunction of our software products is to check that files in the product location have all necessary permissions: open program location, select it, click right button of the mouse and select "Properties" at the pop-up menu. At the property dialog check and make sure that application has all available permissions. "Run as administrator" option could be necessary in some settings.
If nothing is working do contact your Windows Operating System vendor...

What kind of User Account Control interuptions are most troubling?

At Windows 10 there is sometime an appearance of dark blue windows like this:

with strong warning about running unrecognized app (as if Microsoft has legal authorities to monitor and certify all new software applications). Most troubling aspect of this  is absence of direct way to proceed... User must at first to click at "More info" link to reach other dialog box:

with button "Run anyway" that will resolve the issue.

Can license been transferred to other computer?

In most cases the answer is No until you have second computer with the same name and the same user name. It could be violation of copyright laws also, you know.

What term "indefinitely" means related to the term of license?

If you have bought "indefinitely" license it means that we will make no special effort to limit time of license at the computer for the user bought it with specific Registration ID. If license will be lost by user we will not accept any obligation to renew it.
A monthly "indefinitely" subscription means that until cancelation of the subscription at PayPal site by user or LeoKrut it will be renewed automatically at the price established at the start of subscription.

Can user buy new license before term of previous one is expired?

Maybe but doing this user will be in a breach with standard operation procedure and lost of bought time is possible. The right behavior is to wait of expiration of license and redirection to the "buy license" page. To avoid interruption of the service we recommend to subscribe or to choose a longer term license.

What to do if you make a purchace of the license and application does not register anyway?

Be sure that your computer is connected to the internet during first run after purchacing a license. If you already receive notification e-mail do please wait some reasonable time to be sure that we got notification as well. If after a hour or so of receiving notification e-mail LeoCalculator is not registered do contact us by e-mail with all relevant information and we will make all efforts to fix a problem or will refund your money. We are reserving a right to reject a claim of wrong application behavior if we reasonable suspect that it is part of efforts to hack our copyright protection system.
