R.S. If the program does not see the Hantek 1832c, then you need to go to the Device Manager and install the "USB Test and Measurement Devices" driver, which is located on the computer after installing the program.

the main problem now - how to calibrate 1832C on 50, 75, 100khz frequencies.

I think that the calibration for freq 50, 75 and 100 khz are made in 1832c no matter is hacked or not, check the video. - Time after 6:32.
I have a question, does anyone successfully connected the Hantek meter with the Hantek1803C ver 1.0.7 Windows software? I tried everything.

Here is my post at Hantek BBS few months ago regardig software to work with Win 11
https://www.eediscuss.com/forum.php?mod=viewthread&tid=18106&extra=page%3D1
After 2 days exploring now I found that LCR Meter connects to win 11 only by VISA drivers installed on PC.
do not install the supplied virtual com drivers by STM on pc ,the meter does not communicate with this com driver 100% as it is looking for VISA command set.
Drivers from Keysight https://www.keysight.com/in/en/lib/software-detail/computer-software/io-libraries-suite-downloads-2175637.html
Keysight IO Libraries Suite 2023 Update 1 works with my setup.

not exactly, it passes calibration procedure but not saved corresponded variables in the memory, so on those frequencies measurements are not correct.

I confirm what you have written on this forum, no calibration for freq 50khz-100khz. I made the measurements and indeed for 50khz a measured resistor the Theta angle moves from 0 to 50, and for 100khz even gone to 80degrees.
So, i read about this intervention in the passive components in the LCR meter, particularly C66-C69 capacitor on the PCB. Here https://www.creationfactory.co/2021/03/reverse-engineering-and-unlocking.html?showComment=1622733342560#c2775361835350856538 and on page 2 and Page 4 on this forum post. On page 4 user MIRW, suggested "it's not just the firmware you need to change, you have passive parts too, you mean replacing C66 and C67 with 10 and 100 pf".
So, has someone replaced these capacitors, and obtained the calibration? And what type are these capacitors 1206, 0806 or 0603SMD so I can order from AliExpress?
Someone has even suggested that removing these capacitors the meter works fine "If these capacitors are in 1833, then their capacity should be 3 times less, parallel to the 100kOhm calibration resistor was a 22pF capacitor, 10kOhm - 245pF. The device works great without these capacitors at all. It may be necessary to adjust at high frequencies by installing capacitors, but the capacitance must be calculated for a 100kHz filter." from the website - https://www.creationfactory.co/2021/03/reverse-engineering-and-unlocking.html?showComment=1622733342560#c2775361835350856538
