Hi All !!! I I just start working with ASIO SDK2.0 but samplehost don't want load my driver. In "asiolist.cpp" call of "CoCreateInstance()" returns "REGDB_E_CLASSNOTREG"(0x80040154) -------------------------- rc = CoCreateInstance(lpdrv->clsid,0,CLSCTX_INPROC_SERVER,lpdrv->clsid,asiodrv); if(rc == S_OK) { lpdrv->asiodrv = *asiodrv; return 0; } else if (rc == REGDB_E_CLASSNOTREG) I GOT HERE-> ;//strcpy (info->messageText, "Driver not registered in the Registration Database!"); -------------------------- Why it is? There is in registry correct "InProcServer32" entry with pathname & threaing model. But it's doesn't help. What I omitted in addition to this? -- Best regards, ns mailto:neslon@xxxxxxxxx ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
