This information about the crack may interest you as well (translated by Google, from http://forum.ru-board.com/topic.cgi?forum=35&topic=48614&start=1180#11):

Let's start with the fact that the protection of the program is implemented in an extremely original way in the rxfcv.sys driver.

The trial expiration check is located in the encrypted CPATA section, and the registration key check is in the packed EXTRA section.

At the same time, the integrity of some sections of the rxfcv.sys driver is fully or partially controlled by the driver itself.

Therefore, any attempts to solve the problem of registering the program with the help of patches of the FancyCcV.exe and rxpcc.exe files are useless.

Many will probably have a reasonable question — why then do we need these modified files?

The fact is that they are not intended to solve the problem of registration, but to solve one important problem of the trial.

The rxfcv.sys file is a filter driver for Volume class devices.

For this reason, he cannot stop working at an arbitrary point in time or upon the expiration of the trial.

Removing the rxfcv.sys driver from the LowerFilters chain requires a restart or shutdown of the computer.

If, after the first reboot after installing PrimoCache, you no longer restart or turn off the computer, then we have an endless trial.

More precisely, a conditionally infinite trial with the limitations described below and exactly until the next reboot, power off or power failure.

In the light of the above, the logical decision of the developers was to simulate the inability to manage caching tasks after the trial expires.

It is to bypass this «surprise» that the modified files are offered, intended for sharing with TrialReset.

The developers left an additional «trap» for researchers of the trial expiration simulation mechanism.

Tasks and statistics are no longer displayed in the graphical interface when manually transferring the date beyond the boundaries of the trial.

The driver itself is responsible for this trick, which reacts in such a harsh way to date manipulations.

Therefore, this effect is observed when using both original files and modified ones.

After the date passes beyond the boundaries of the trial, tasks and statistics do not disappear during the natural course of the system clock.

The difference between the modified and original files in this situation becomes noticeable only in one moment.

The original files will not allow you to manage caching tasks if these files were launched after the trial expired.

The modified files are designed to bypass these artificial caching task management restrictions.

The difference between the modified Registered, Subscription and Trial files is purely cosmetic.

Just choose among them the most suitable «licensing» option for you:

• Registered — the name speaks for itself;

• Subscribe — a non-expiring subscription for 365 days with a correct recalculation of the new expiration date at each launch;

• Trial — a non-expiring trial with a final stop of the counter for 0 days with a full-fledged continuation of work.

An alternative to modified files is to use the PrimoCache icon menu in the notification area.
