[Office 2007 plugin error] Could not open OOXML (error reading from: C:\Users ...etc.

[rkg82]

As a follow-up, and to conclude for the time being, I've included at the end of this message the results for two successive runs of the same offline configuration over the same data set, the only difference being in the number of threads used, nine for the first run, one for the second.

For some reason multiple-thread runs produce slightly better results: in some but not all cases, about 3 to 9 percent more files were reported as being indexed, than in single-thread mode. In both modes, the same 127 files were reported as "Errors" for both runs. It is not clear what the status of the other unindexed files was. For example, plain text files, 706 indexed in multiple-thread mode, 704 in single thread mode.

Among the "hard-core set" of 127 problematic files:

- About 40 Excel files from a particular sub-group of files stored on our GitHub server turned out not to be real Excel files at all, but symbolic links that when downloaded from our GitHub server appear on the local file system as normal Excel files, but only 1 KB in size.

- About 50 Word files from an particular sub-group of files stored on our SVN server are old Word .doc files which can be opened locally, but not indexed. This may be related to their format, as they were all created with legacy versions of Word about 10 years ago.

- All remaining files are various Excel, Word, or PowerPoint files, mostly unrelated, and stored in various places on our SharePoint server. Local copies of these can be opened, but not indexed, for reasons that remain unclear to us.

[Ray]

Can you confirm you are using the latest build (V8.0 build 1007) as available here:
https://www.zoomsearchengine.com/zoo...w.html#windows

There has been a few related issues fixed since build 1006.

[rkg82]

Yes, using v. 8 build 1107

[Ray]

If you want us to investigate further, you can email us a few sample files from this group, along with your ZCFG settings:

All remaining files are various Excel, Word, or PowerPoint files, mostly unrelated, and stored in various places on our SharePoint server. Local copies of these can be opened, but not indexed, for reasons that remain unclear to us.

[rkg82]

Unfortunately, I cannot provide the actual files, for reasons of confidentiality. I'd have to strip all content from them. I'll try to send one or two stripped ones next time I come across a new file that fails to index the first time, or after having been successfully indexed previously. I already provided one such stripped version of one of the files subsequent to our exchanges in the other thread I started.

[Ray]

We reproduced the problem with the previous stripped file you gave us, and fixed the problem such that it no longer occurs with the latest build. So there may be a different problem with these other files.
