Terminal output of Hygeia Pharmacy running under Wine
Hygeia Pharmacy is a .NET 4 application for pharmacy retail. When the
application starts up, it will check for various shared components, ending up
complaining that Microsoft Report Viewer has to be installed despite already
installed.
Attached is the screenshot of the error. It says, "It's necessary to install an
additional programed named Microsoft Report Viewer"
("มีความจำเป็นต้องติดตั้งโปรแกรมเสริมที่ชื่อว่า Microsoft Report Viewer").
Terminal output reveals 2 interesting FIXME's:
```
0174:fixme:msi:MsiProvideAssemblyW L"Microsoft.ReportViewer.Common,
Version=10.0
.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a,
processorArchitecture=MS
IL", L"C:\Program Files\HygeiaPharmacy\HygeiaPharmacy.exe.config", 0, 0,
10D7
A618, 10D7A614
0174:fixme:msi:MsiProvideAssemblyW L"Microsoft.ReportViewer.Common,
Version=10.0
.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a,
processorArchitecture=MS
IL", (null), 0, 0, 10D7A618, 10D7A614
```
This leads me to believe that the application chokes up because it does not
receive the correct path to this .NET assembly, part of MS ReportViewer 2010.

Looking into multiple documents and into Wine itself, I _think_ it would be
relatively simple to implement MsiProvideAssembly[A|W]() using facilities
already implemented in Wine. Bug 58577 plays an important role on this.
I actually would love to get my hands dirty, if not for 2 problems:
1. I don't actually have much time myself.
2. Many years ago, I disassembled a different component of Windows (related to
MDM/management policy) in order to debug my graduating project. I forgot
everything by now, and it's IMHO not related, but combined with 1. I think it's
probably better to stay safe.
(Can I explain some high-level idea? Will I run afoul of 2.?)
A number of MSDN documents that might be useful:
https://learn.microsoft.com/en-us/windows/win32/api/msi/nf-msi-msiprovideass...
https://learn.microsoft.com/en-us/windows/win32/msi/assembly-registry-keys-w...
Also helpful is a small test program I write myself to exercise
MsiProvideAssemblyW() in the same way as the application (and in a slightly
different way). On Windows 11, this outputs as follow:
```
MsiProvideAssemblyW("Microsoft.ReportViewer.Common, ..." (qualified)) returns 0
Returned path (119):
C:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.Common.dll
MsiProvideAssemblyW("Microsoft.ReportViewer.Common" (unqualified)) returns 0
Returned path (119):
C:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.Common.dll
```
On Wine, it outputs (excluding Wine's output itself):
```
MsiProvideAssemblyW("Microsoft.ReportViewer.Common, ..." (qualified)) returns
120
MsiProvideAssemblyW("Microsoft.ReportViewer.Common" (unqualified)) returns 120
```

Following is the way I run Hygeia Pharmacy.
Hygeia Pharmacy is a relatively complex application and requires the full .NET
installation (Mono is not enough). The following commands recreate the
environment from scratch:
```
export WINEARCH=win32
export WINEPREFIX=/a/new/prefix
winetricks dotnet48 jet40 mdac28
wine ReportViewer.exe # sha256sum:
e8ff182e202b321ac2b9245ee20c4eb659008ffb2a34cdbd3486f9da3d4c3e06
wine hygeia_trial_install.2.6.28.1.exe # sha256sum:
380085defb0af240f144d603da70d09a76c940a27a65953a9fbe3668c321b4e2
wine "C:\\users\\Public\\Desktop\\Hygeia Pharmacy.lnk"
&>hygeia_pharmacy_wine_output.txt
```

The (trial) version can be obtained from
https://www.hygeia-pharmacy.com/trial/. However, it requires a (free)
registration, and the website is entirely in Thai with no English version.
In order to (try to) help you with the registration, the registration page at
https://www.hygeia-pharmacy.com/register/ requires the followed:
1. A chosen username ("Hygeia ID")
2. A chosen password.
3. Your full name
4. Your email.
5. A math captcha (input the equation's answer).
I can't remember if there's an email verification after that step or not,
because it's been a long time since I registered myself.
Once logged in, https://www.hygeia-pharmacy.com/trial/ will show a big blue
button for downloading the trial version. The same page will also be a smaller
link for "MS Report Viewer" which is hosted by Hygeia Pharmacy themselves (if
you prefer an MS link, see the end of bug 58577).
