3.5.0b2 wants a lot of free space: 430 MB on system drive + 300 MB on selected destination drive. The latter is expected. I wonder what the former is for. NB: This is after the .msi file is copied to %TMP% at very start of installation process. PS: Obviously, I noticed because I don't currently have so much free space on my system drive :-< *** I don't think v3.3.x-v3.4.x .exe installer needed (that much) space on system drive.
It's the space required for uncompressing the temporary installation files. A little less than 500 MB for LibO 3.5.0. With the NSIS, it used to ask where to decompress the files. But now with the MSI, it just decompresses them on the system drive during the install.
Thanks for checking. Thankfully, LibO provides PortableApps installers :-) I will have to manage by using them...
