[Qgis-user] Grid shift FIle for MSI version

[Dario C]

Hi,

I'm working on a 3003 project with 7791 layers. Once I updated to 3.16.10
msi release I received this message:
*"The preferred transfer between EPSG: 7791 - RDN2008 / UTM zone 32N and
EPSG: 3003 - Monte Mario / Italy zone 1 is not available for use in the
system.*

*This transformation requires the lattice file
"35160622_47161840_R40_F00.gsb", which is not available for use on the
system.The current transformation "Inverse of UTM zone 32N + Ballpark
Geographic offset from RDN2008 to Monte Mario + Italy zone 1" has an
unknown accuracy, while the current transformation "Inverse of UTM zone 32N
+ Inverse of Monte Mario to RDN2008 (5) + Italy zone 1 "has an accuracy of
0.1 meters."*

and actually I have translated projection between 7791 and 3003 (around 100
meter)

I tried to install 3.16.10 exe (instead of msi) and everything works well.

Is it a bug or I just need a .gsb file? In this case, where can I find .gsb
file? Thank you

cheers
