Try install Microsoft Visual C++ 2010 Redistributable Package (x64)

I'll give that a try tonight.   Would be nice to build up a list of requirements for the software,  considering it's not really documented at all.
I'm also waiting on a reply from Qihe to see if they have a hardware/software requirements list.

The other piece of the puzzle that was required was .net framework 3.5
Thankfully that self-identified and was easy to install after making sure the Win10 was fully updated.

Unfortunately adding the C++ redistributable didn't help in my case.   Tried all the versions that are on my main PC (which can open the software), with no success.
Also tried an earlier revision of the surface mount program.  Again, no success.
Waiting on a response from Qihe as well. 

I may still end up having to grab a crusty old Win7 machine after all.  Which would be unfortunate as a mini-PC could fit inside the pick and place and give me a real clean result.

Qihe got me sorted out.   It requires the C++ 2010 Redistributable Package 32bit,  not the x64
You were definitely on the right track there, definitely appreciate it.

Took me a bit to get the vision drivers all sorted out but it's running now.
Also turned off the packet coalescing as well.

my machine (TVM802A)  is equipped with the Juki nozzles and came with software v3.03
I wonder what the latest changes have been.

Can you share screenshot of the software please ? i have 2.36V

I'll see what I can do,  it's not on my main network.   Any particular feature you'd like to see?
I also have a rev change log that shows the changes in the 3.XX series up to this point.

As I understand it,   there were some hardware changes and older version machines can't run this version software.

V3.03? Qihe send me the latest one just today and it's according to what they send V2.37.

The RAR pack now has a change log in docx format (I made it PDF)

Quick question: how you do the offset between the fiducials and the parts? Seems I forgot how to do that.

Apparently there was a hardware change,  and v2.3x would be the branch for the older hardware, while the 3.0x is for the newer hardware.

I haven't pulled mine apart yet to see what's on the inside.

How do you do panels with that PnP?

My PCB has 4 panels, I setup the fidicials on the PCB setup, I enabled the 4 PCBs. The PnP gets parts for 4 PCBs - but places all parts in PCB #1.

What did i do wrong?

There are two types of coordinates, MARK and REAL, mark is the coordinates in cad design pcb software and real is the own pick and places coordinates. In mark field (PCB1, PCB2, etc.) there should always be the same value and you just have to change the real coordinates of p&p. See the picture.

Mhm, in 'Mark' I put the location of the 4 individual fiducials on each of the 4 PCBs, and in REAL I put the real location of on each of the 4 PCBs. Not correct?

Not correct, all mark fields must have same coordinates, and in the real coordinates i see some errors too.

I still don't get it. Now I set all gerber mark points to PCB1 - now the PnP finds the 4 PCBs in the panel - but now the X has about 5mm offset, even though the real PCB mark points are found very accurate.

That's the coordinates according to Gerber.

Yes, so what coordinates you mean? That is it the actual placement of the parts.

I'm now working with the TVM802B for almost 2 years and have manufactured several thousands of boards.

From my experience the machine is mechanically very well done. Even after 2 years all is working well.

The big problem is the camera which does not detect all parts as good as required.
This could be improved by an additional field in the parts list: an X and Y correction-offset for CAM1.

Maybe the responsible Chinese people take this as an idea for future software releases.

Does anyone have a link to QiHe Vision Mounter 2.37 (or whatever the newest version is)?

I just purchased this machine and I'm wondering (and hoping) it can place SOT-45 with no issues. My design relies heavily on them. Does anyone have experience with SOT-45 using the TVM802?

Thanks!

to be honest, I never have seen SOT-45 case.
Can you please give us the part number of this component.

As a general rule of thumb, the TVM802 can please components in 0603 size quite well.
Its not ideal for smaller components, in which case you will need to correct it under the microscope before soldering.

Apologies, I meant SC-74/SOT-457
