@ADMINS ANY UPDATES ??
Still receiving same "-195 errors" with the _4 tasks.

"195" error is a generic error from BOINC, not specifically in regard to the app.

your CPU is over 15 years old and lacks modern features such as SSE4 and AVX. this probably the reason they all fail.

the Gaia_5 and Gaia_6 apps probably do not require this, which is why they work.

That could be an interesting research Project to be done here on the returns

i checked 20 of the successful resends from his most recent 20 errors. and all were newer systems with more modern instruction sets. the oldest system that a resend successfully completed was on an i5-4250U, which supports SSE4/AVX/AVX2.

there's a strong correlation here. but also very unlikely that many people are running such old hardware anyway so pretty unlikely that a resend would go to such an old system.
