Garden solar light teardown

Bought 3 cheap garden solar lights, each < 1.00 Eur just to see how do they work. One did not work from the start. Another stopped working after a weak. Third worked well during all summer.
One had: circuit with a chip marked 5252F 1109, Ni-MH battery 2/3AA 300mAh 1.2V. Another with YX8018 0157 chip, Ni-MH battery 2/3 AAA 300mAh 1.2V.
Some Googling for those chips leads to these similar circuits:

PowerBuilder 8 OLE insert crash

I had same work with an old PowerBuilder 8 application maintenance and upgrade. While trying to add OLE control to a windows PB constantly crashed. PB and Windows XP reinstall didn’t helped. I found a hint here http://brucearmstrong.wordpress.com/2007/07/10/problems-using-activex-controls/

In short:
1. Download Process Monitor
2. Add filter to pb80.exe process and path that begins with HKCR\CLSID
3. Try to add OLE with PB (make it crash)
4. Find last entry that ends with Control, search this CLSID with regedit
5. Reregister dll You found.
In my case it was regsvr32 %systemroot%\system32\mstscax.dll
Problem solved.
