Windows 7 64-bit - known problems?

[Karbon]

I'm just moving to PureBasic 4.51 and the only userlibs I use are Paul's from PureVision (PVGadgets).

I'm using the 32-bit version of PB (though it's running in 64-bit version of Windows), just like I was with PB 4.4

When compiling a piece of code that uses PVGadgets I get this :

POLINK: error: Unresolved external symbol 'SYS_FreeArray'.
POLINK: error: Unresolved external symbol 'SYS_AllocateArray'.

At first I thought PureVision might have been installing the 64-bit library but if I xcopy my purebasic folder to a VMWare machine running a 32-bit version of Windows 7, everything compiles and links just fine.

I've spoken with Paul and he says it all works for him so I'm at a loss as to what could he happening. I've completely uninstalled and reinstalled PureBasic and PureVision a number of times to verify everything is fresh and keep getting the same thing.

Does anyone have any ideas?

in PB4.51 it must be _SYS_FreeArray@4 and _SYS_AllocateArray@20 !
So most likely its a third party lib that has to be recompiled with PB4.51.

The only problem with that being true is that the exact same userlib and purebasic (I xcopied the whole PB directory) works on Windows 7 32-bit.

have you searched your harddisk for the pvgadgets library ? i bet its a leftover from an older version, maybe virtualized by Windows

Yep, spot on. It was virtualized.. I had to use a 3rd party search to find it though - the virtual folders weren't searched by the built-in Windows search.

Thanks!

If anyone is interested as I was in how you turn virtualization off :

Click start and type "secpol.msc" in the search box, hit enter.

Local Policies > Security Options > UAC: Virtualize file and registry write failures to per-user locations - Set to DISABLE.
