Solve the problem of unable to load R3 module… Vboxdd.dll (vboxdd): GetLastError = 1790

Solution: restore the system theme file

due to the demand, I downloaded and installed [VirtualBox 4.3.18 for windows hosts] in my windows 7 (64bit), and there was no error in the installation process

but the following error will appear when loading xxx.iso

then, I went to check whether there are Chinese characters in the installation path, and found that it is directly installed under disk D. (note that it is not the problem here.)

in the end, there was no solution. I went to consult Du Niang and found that Du had encountered this problem. It was said that it was the reason why the theme file of windows system was cracked. At that time, I also wanted to know why it had something to do with it. Based on the principle that it was not my own computer, I downloaded the theme cracking and restoring tool provided by du you, Ya’s really solved this problem. So there’s this nonsense.
