My boss reported a problem with a new ACER portable PC using Windows 7 family premium 64 bit edition. (rawdisk driver was never installed before on this PC)

It seem that none of the 3 drivers (elrawdisk.sys,elrawdisk64.sys ,elrawdiskia64.sys) are accepted by the TRawdisk.InstallDriver() function.

The path is correct , the 3 files exist but the function returns always "false" with a Windows.GetLastError=0 (no error) ... no matter which file is loaded

The only "strange thing" on this pc is that the "c:\program files" directory seems to be renamed to "c:\programs files (x86)".

Any idea on what could cause this issue ?

It's not strange - this is the way 64-bit windows works. You need to install the driver for x64 platform. Did you check your application with any other 64-bit system?

I have forced the application to load the 3 drivers (one after one) to be sure that this is not a file version mistake.

And of course the application runs fine on several other 64 bits systems , this is the first time this issue is reported.

Is the application run from Adminstrator account? Please ensure that it's so.

I presume this is the case but I asked the person that has access to the computer to test again with "execute as an administrator" the whole app, even if I make an elevation of priviledges just before installing the driver.

If will have an answer tomorrow, office is closed now ;)

Ok it seems this is an elevation problem, it seems that the code I use is not compatible with windows seven :-(

So no driver problem so far.
